Once Messenger of Allah ﷺ heard the loud voices of some opponents quarreling at the door. One of them was appealing to the other to deduct his debt and asking him to be lenient but the other was saying, "By Allah I will not do so." Messenger of Allah ﷺ went out to them and said, "Who is the one who was swearing by Allah that he would not do a favor?" That man said, "I am that person, O Messenger of Allah ﷺ! I will give my opponent whatever he wishes."  

سَمِعَ رَسُولُ اللَّهِ ﷺ صَوْتَ خُصُومٍ بِالْبَابِ عَالِيَةٍ أَصْوَاتُهُمَا وَإِذَا أَحَدُهُمَا يَسْتَوْضِعُ الآخَرَ وَيَسْتَرْفِقُهُ فِي شَىْءٍ وَهْوَ يَقُولُ وَاللَّهِ لاَ أَفْعَلُ فَخَرَجَ عَلَيْهِمَا رَسُولُ اللَّهِ ﷺ فَقَالَ أَيْنَ الْمُتَأَلِّي عَلَى اللَّهِ لاَ يَفْعَلُ الْمَعْرُوفَ فَقَالَ أَنَا يَا رَسُولَ اللَّهِ وَلَهُ أَىُّ ذَلِكَ أَحَبَّ  

Messenger of Allah ﷺ 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 Messenger of Allah ﷺ 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.  

سَمِعَ رَسُولُ اللَّهِ ﷺ صَوْتَ خُصُومٍ بِالْبَابِ عَالِيَةً أَصْوَاتُهُمَا وَإِذَا أَحَدُهُمَا يَسْتَوْضِعُ الآخَرَ وَيَسْتَرْفِقُهُ فِي شَىْءٍ وَهُوَ يَقُولُ وَاللَّهِ لاَ أَفْعَلُ فَخَرَجَ رَسُولُ اللَّهِ ﷺ عَلَيْهِمَا فَقَالَ أَيْنَ الْمُتَأَلِّي عَلَى اللَّهِ لاَ يَفْعَلُ الْمَعْرُوفَ قَالَ أَنَا يَا رَسُولَ اللَّهِ فَلَهُ أَىُّ ذَلِكَ أَحَبَّ
