Sahih Muslim , Hadith 1557 ⓘ
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.
وَحَدَّثَنِي غَيْرُ، وَاحِدٍ، مِنْ أَصْحَابِنَا قَالُوا حَدَّثَنَا إِسْمَاعِيلُ بْنُ أَبِي أُوَيْسٍ، حَدَّثَنِي أَخِي، عَنْ سُلَيْمَانَ، - وَهُوَ ابْنُ بِلاَلٍ - عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ أَبِي الرِّجَالِ، مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ أَنَّ أُمَّهُ، عَمْرَةَ بِنْتَ عَبْدِ الرَّحْمَنِ قَالَتْ سَمِعْتُ عَائِشَةَ، تَقُولُ سَمِعَ رَسُولُ اللَّهِ صلى الله عليه وسلم صَوْتَ خُصُومٍ بِالْبَابِ عَالِيَةً أَصْوَاتُهُمَا وَإِذَا أَحَدُهُمَا يَسْتَوْضِعُ الآخَرَ وَيَسْتَرْفِقُهُ فِي شَىْءٍ وَهُوَ يَقُولُ وَاللَّهِ لاَ أَفْعَلُ . فَخَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم عَلَيْهِمَا فَقَالَ " أَيْنَ الْمُتَأَلِّي عَلَى اللَّهِ لاَ يَفْعَلُ الْمَعْرُوفَ " . قَالَ أَنَا يَا رَسُولَ اللَّهِ فَلَهُ أَىُّ ذَلِكَ أَحَبَّ .
