In Hadith, it is mentioned that Kumayl ibn Ziyad said, "I was sitting with my master Amir al-Mominin ‘Ali ibn Abu Talib (peace be upon him) in Masjid Kufa and a group of companions were also sitting with him. One of them asked him what the meaning of the verse 'Whereupon every wise command is made clear.' (Surah ad-Dukhan, Verse 4) The Imam (peace be upon him) replied, The meaning of this is the night of the 15th of Sha‘ban. I swear by the One who holds the life of ‘Ali in His hands there is not a single servant of Allah except that all the good and bad that will reach him in this year is divided up and handed out on the 15th of Sha‘ban and this good and bad will continue from the 15th of Sha‘ban until the next year on the same night. The servant who stays up this night and recites the Du‘a of Khidr will have his supplications answered." This dua taught to Kumayl ibn Ziad is now known popularly as Dua e Kumayl.
