Riyad as-Salihin 250
'Aishah (May Allah be pleased with her) reported:
Messenger of Allah (ﷺ) heard the voices of altercation of two disputants at the door; both the voices were quite loud. One was asking the other to make his debts little (so that he could pay them) and was pleading with him to show leniency to him, whereupon the (other one) said: "By Allah, I will not do that". Then there came Messenger of Allah (ﷺ) to them and said, "Where is he who swore by Allah that he would not do good?" He said: "O Messenger of Allah, it is me. Now he may do as he desires". [Al-Bukhari and Muslim] .
وعن عائشة رضي الله عنها قالت‏:‏ سمع رسول الله صلى الله عليه وسلم صوت خصوم بالباب عالية أصواتهما، وإذا أحدهما يستوضع الآخر ويسترفقه في شيء، وهو يقول‏:‏ والله لا أفعل، فخرج عليهما رسول الله صلى الله عليه وسلم فقال‏:‏ “أين المتألي على الله لا يفعل المعروف‏؟‏ ‏"‏ فقال‏:‏ أنا يا رسول الله ، فله أي ذلك أحب ، ‏(‏‏(‏متفق عليه‏)‏‏)‏ ‏.‏
