The Love (Muhabbat) and Wilayat of Hazrat Ali (a.s.) is a Guarantee of True Safety and Protection
The real and true guarantee of protection from the terrible fright on the Day of Judgement is the Wilayat and Muhabbat of Amirul Momineen (a.s.). It is called Husnaa (the greatest good). No other good can surpass this good. Everyone having this good in his heart will remain safe on the Day of Qiyamat: Innal…Akbar (Surah Anbiyaa: 21, V: 101-104).
Translation: Verily those who will get the greatest from us in advance will remain far away from Hell. They will not even hear its humming and will always be enjoying their choice bounties. Even the terrible fright of Qiyamat will not trouble them. The Holy Prophet is reported to have said that: O Ali! You and Your Shias (followers) will remain in peace from the Faza-e-Akbar (the terrific fright). And this refers only to you.
The Absolute ‘Hasana (Good) Is The Wilayat Of Ali Bin Abi Talib Similarly, the Hasanah which is the absolute good is the Love and friendship of Ali (a.s.) and the Aal (progeny) of Ali (a.s). Quran has given promise that, on the Day of Resurrection, the one who will come with Hasanah will get the best reward and he will remain in peace from the fright of that Day: Man Jaa…Aaminoon (Surah Naml: 27, V: 89). Translation: The one who will do good will get a far more better reward and these people will remain safe and in peace from the danger and fright of that Day.
In the tafseers (commentaries) of the Sunnis, such as Tafseer-e-Kashshaaf-e-Zamakhshari and Tafseer-e-Kabeer-e-Fakhre Raazi and Tafseer-e-Tha'labi and Tafseer-e-Rooh-ul-Bayan etc, it is mentioned that the Holy Prophet (s.a.w.s.) said that the one who dies with the love of and friendship with Aale Muhammad (a.s.) in his heart will die as a repentant and clean and when he will be raised from the grave he will enter the grand field of gathering (Mahshar) happily. He will neither feel fright nor any uneasiness. Paradise will be decorated for him just the bridal apartment is being adorned for the bride…(till the end of the lengthy narration). What I wanted to present was the part showing that the friends of Ali (a.s.) will be in peace in Qiyamat.
The Divine Virtues of Imam Ali (A.S.) and the Holy Ahlul Bayt (A.S.)
Quoting the Holy Prophet (SA) Sunni and Shi'ah 'ulama' have related many ahadith on the virtues of 'Ali (AS) and all the other Ahl al-Bayt. Three of these virtues will be dealt with here.
(1) In the 6th year after Hijrah, the Christians of the city of Najran selected a group of their dignitaries and scholars and sent them to Madinah. The delegation primarily debated and argued with the Holy Prophet (SA), but they were condemned and defeated and Allah revealed the following Ayah of "Al-Mubahalah (cursing)".
"But whoever disputes with you in this matter after what has come to you of knowledge, then say: 'Come let us call our sons and your sons and our women and your women and our near people and your near people, then let us be earnest in prayer, and pray for the curse of Allah on the liars' (3:61)." According to the order and instruction given through this Ayah, the Holy Prophet (SA) proposed that the Christian delegation from Najran participate in requesting the curse of Allah on liars, that is, they had to gather along with their wives and children to pray for the curse of Allah on the liars, so that the Almighty Allah would send upon them His torment.
The Christian delegation from Najran accepted the proposal for Al-Mubahalah and allocated the day after for this purpose. The next day, a great number of Muslims and also the delegation from Najran waited for the Holy Prophet's (SA) appearance to see in what form and with what formalities he would arrive and whom he would bring along for Al-Mubahalah. They saw the Holy Prophet (SA) coming out in such a way that he was carrying al-Husayn (AS) in his arms and holding al-Hasan's (AS) hand in his hand. Behind the Holy Prophet (SA) was his daughter, Fatimah (AS), and behind her was 'Ali (AS). The Holy Prophet (SA) ordered these honourable persons accompanying him to say Amin (may it be so) when he prayed.
The delegation of Najran was struck with horror when they saw this holy delegation who entirely displayed truth and reality and who sought no refuge except the protection of the Almighty Allah. The chief of Najran delegation told his colleagues; "By Allah, I see these faces who will annihilate all the Christians of the world if they turn towards Allah." This was the reason why they came to Muhammad (SA) and asked him to excuse them from participating in Al-Mubahalah. The Holy Prophet (SA) asked them to submit to the will of Allah and convert to Islam. They said that they were unable to fight with the Muslims but were ready to pay annual tax to live under the protection of Islam. Thus this episode ended. The following conclusion could be drawn from this incident: The accompaniment of 'Ali (AS), Fatimah (AS), al-Hasan (AS), al-Husayn (AS) with the Holy Prophet (SA) in the course of Al-Mubahalah clarified that, in the holy Ayah "our sons, our women, and our near people" refers to none but the Holy Prophet (SA), 'Ali(AS), Fatimah (AS), al-Hasan (AS), and al-Husayn (AS). In other words, by stating the word "ourselves", the Holy Prophet (SA) meant himself and 'Ali (AS), by "our women", he meant Fatimah (AS), and by "our sons", he meant al-Hasan (AS) and al-Husayn (AS).
Thus, it becomes crystal clear that 'Ali (AS) is in the same rank as the Holy Prophet (SA) himself. It also becomes evident that the Ahl al-Bayt (AS) of the Holy Prophet (SA) were four persons. This is because the members of the household of anyone are those which are commonly called as "ourselves, our women, and our children". If any other persons were considered as the Ahl al-Bayt, the Holy Prophet (SA) would have taken them along for Al-Mubahalah.
This is why we must judge about the 'Ismah (infallibility) of these four persons, for the Almighty Allah testifies on the 'Ismah and taharah (purity) of the Ahl al-Bayt (AS) of the Holy Prophet (SA): "...Allah only desires to keep away the uncleanliness from you, O Ahl al-Bayt! and to purify you a (thorough) purifying (33:33)." (2) As related by Sunni and Shi'ah 'ulama', the Holy Prophet (SA) has stated: "The parable of my Ahl al-Bayt is that of Nuh's ark; those who boarded were saved while those who did not board were drowned".
(3) In another successive hadith, related by Sunni and Shi'ah 'ulama', the Holy Prophet (SA) has stated: "I leave two valuable things for you which will never be separated from each other till they meet me at Hawd al-Kawthar. They are the Allah's Book, Quran and the Ahl al-Bayt. You will not go astray after me as long as you remain in touch with them intimately and seek refuge under these two".
Imam Ali (A.S.) and Hadrat Fatima (A.S.) in Hadith
"Fatima is a human huri, whenever I long for paradise I kiss her."?  or: "My daughter Fatima is a human huri."  or: "Fatima is the true splendor."  or with Anas Ibn Malik's Mother saying: "Fatima was like a moon on its full night, or the sun covered with no clouds. She was white with a touch of rose color on her face, her hair was black and she had the beautiful features of the Messenger of Allah (S)”  or Aisha's saying: "I have not seen a person more similar to the Prophet's appearance, conduct, guidance and speech whether sitting or standing than Fatima. When she enters, the Messenger of Allah stands up, kisses and welcomes her, then takes her hand and asks her to sit in his place."  Also in Bihaqi's quotation in Sunah vol. 7, p. 101, Aisha said: "I have not seen anyone more similar to the Messenger of Allah's habit of speech and dialogue than Fatima... " The Holy Prophet (S.A.W.) says to Ali (A.S.) "Your conduct and looks are similar to mine, and you are from the same tree from which I came."  While the Prophet declared that Ali was the best man of his nation, for he was the most patient and best mannered one of them all, and says: "Ali is the best of my nation, most knowledgeable and most patient from among them”  The Holy Prophet (S.A.W.) say to Fatima? "I gave you in marriage to the first one to adhere to Islam from my nation, he is also the most knowledgeable and most patient among them?"  and: "I gave you in marriage to the first Muslim and best mannered man."  "He was the first to believe in me, and he will be the first to shake my hand on the Day of Rising!?" He also informed his companions that: "The first among you to appear at my domain (reservoir), is he who was the first among you to follow Islam Ali Ibn Abu Talib." Or with that which was narrated in the story of the roasted bird?which is mentioned in the Sahihs and Musnads?when the Prophet said: "O Allah, bring the most beloved creature to You so that he may eat with me." or when he said to Aisha: "Surely Ali is the most beloved of all men and the most precious to me. Therefore, recognize his rights, and pay tribute to him."  And: "The most beloved of all men to me is Ali.”  And: “Ali is the best of those whom I leave behind me (after death)."  And: "The best of your men is Ali Ibn Abu Talib, and the best of your women is Fatima Bint Muhammad."  And: "Ali is the best of mankind, and he who denies (this) is an infidel."  And: "He who does not say that Ali is the best of mankind is surely an infidel."  And in Banner's narration where it has been unanimously agreed that he (S) said: "Tomorrow I will hand over the banner to a man whom Allah and His Messenger love, and who loves Allah and His Messenger." And: “Ali to me is like my head to my body."  And: “Ali to me is like I am to my Lord."  And: “Ali is the most beloved to me, and the most beloved to Allah."  He (S) also said to Ali: "I am from you, and you are from me; or you are from me and I am from you.”  And: 'Ali is from me and I am from him; he is the guardian (wali) of every believer after me."  And: ?In the narration regarding sending Ali (A) to read Surah At-tawbah (Surah No. 9) to the pilgrims on which it has been unanimously agreed, he said: "No one takes it (to the pilgrims) except a man being from me and I from him."  And: "Your flesh is my flesh, your blood is my blood, and righteousness is on your side.”  And: "There is not a prophet who has not had a peer, and Ali is my peer.”  Also, in a narration that Al?Hakim deemed authentic, Tabarani related to Umme Salama the following: "Whenever the Prophet of Allah was angered, no one dared to speak to him save Ali.”  Also Aisha said: "(I declare) by Allah that I have not seen anyone more beloved to Allah 's Messenger than Ali, or a woman on earth more beloved to him than his wife (Ali's wife, Fatima)."  Buraida and Ubae also said: "The most beloved to the Messenger of Allah from among women is Fatima, and from among men is Ali.,,  And Juma Ibn Umair said: "I entered Ali's house with my Aunt, when I inquired as to who was the most beloved of all people to Allah's Messenger?! She said: Fatima. Then she was asked: And from among men? She said: her husband, ever since I met him he has been fasting and praying."  "Surely Allah has examined the dwellers of Earth and has chosen your Father to be a prophet, He then examined (them) and chose your husband, then He revealed to me that I give (you to him in) marriage and appointed him as my successor."  He (S) also said to Fatima: "Surely Allah chose two men from the dwellers of Earth, one being your Father and the other your husband."  References:  Tareekh Baghdad by Khateeb Baghdadi: v.5, p.86.
