Sahih Muslim Book 45, Hadith 118
This hadith has been transmitted on the authority of Abu Zinad with a slight variation of wording.
O Allah, I make a covenant with Thee against which Thou wouldst never go. I am a human being and thus for a Muslim whom I give any harm or whom I scold or upon whom I invoke curse or whom I beat, make this a source of blessing, purification and nearness to Thee on the Day of Resurrection.
A hadith like this has been reported on the authority of Abu Huraira through another chain of transmitters.
