Dua Kumayl (, ) is a dua or supplication attributed to Ali, the cousin and son-in-law of the Islamic prophet Muhammad, who taught it to his companion, Kumayl ibn Ziyad. This supplication is used by Muslims to ward off evil and is particularly well-known among Shia Muslims. The latter regard Ali as their first Imam and the designated successor of Muhammad. Historical details According to the Shia scholar Majlesi, Kumayl ibn Ziyad, a confidant of Ali, attended a sermon in Basra by Ali in which he mentioned the night before mid-Sha'ban. In his sermon, Ali said "There is no worshiper who stays awake through this night and recites the prayer of al-Khidr who will not have his prayer answered." After the sermon, Kumayl expressed his interest in learning this dua and Ali dictated it to him. Ali then advised Kumayl to recite this dua on the eve of every Friday, or once a month, or, at least, once a year to ward off evil and receive divine blessings and forgiveness. Shia scholars Tusi and Ibn Tawus both record this prayer under the acts of worship for the night of mid-Sha'ban. In particular, Tusi refers to this prayer as dua al-Khidr and writes that Kumayl (possibly on a different occasion) saw Ali reciting this prayer while prostrating in worship.
