A'isha (Allah be pleased with her) reported: Allah's Messenger heard the voices of altercation of two disputants at the door; both the voices were quite loud. The one demanded some remission and desired that the other one should show leniency to him, whereupon the (other one) was saying: By Allah will not do that. Then there came Allah's Messenger to them and said: Where is he who swears by Allah that he would not do good? He said: Massenger of Allah, it is I. He may do as he desires.
