Concerning the Prayer of Benefits [Salat al-Khair], traditionally performed on the night of mid-Sha’ban
As for the ritual prayer traditional for the night of mid-Sha’ban, it consists of one hundred cycles, including one thousand repetitions of “Qul Huwa’ llahu Ahad [Say:’He is Allah, One!’]” (that is to say, ten repetitions in each cycle[rak^a]). This prayer is called Salat al-Khair [the Prayer of Benefits], and its blessings are many and varied.
Our righteous predecessors used to gather to perform it in congregation. It contains much merit and rich reward. It is reported of al-Hasan al-Basri (may Allah bestow His mercy upon him) that he once said:
“Thirty of the Companions of Allah’s Messenger (Allah bless him and give him peace) related to me that Allah will look seventy times upon one who performs this prayer on this night, and with each glance He will fulfill seventy of that person’s needs, the least of them being forgiveness.”
It is also commendable to perform this prayer on the fourteen nights on which vigil is recommended, as we have mentioned in [the chapter concerning] the merits of Rajab, so that the worshipper may thereby obtain this grace, this merit and reward.
This brings us to the end of the Sixth Discource
Praise be to Allah, the Lord of All the Worlds!
