Sahih Muslim , Book 12, Hadith 125 (In-Book) ⓘ
Abu Umama reported Allah's Messenger as saying: O son of Adam, it is better for you if you spend your surplus (wealth), but if you withhold it, it is evil for you. There is (however) no reproach for you (if you withhold means necessary) for a living. And begin (charity) with your dependents; and the upper hand is better than the lower hand.
حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، وَزُهَيْرُ بْنُ حَرْبٍ، وَعَبْدُ بْنُ حُمَيْدٍ، قَالُوا حَدَّثَنَا عُمَرُ بْنُ يُونُسَ، حَدَّثَنَا عِكْرِمَةُ بْنُ عَمَّارٍ، حَدَّثَنَا شَدَّادٌ، قَالَ سَمِعْتُ أَبَا أُمَامَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " يَا ابْنَ آدَمَ إِنَّكَ أَنْ تَبْذُلَ الْفَضْلَ خَيْرٌ لَكَ وَأَنْ تُمْسِكَهُ شَرٌّ لَكَ وَلاَ تُلاَمُ عَلَى كَفَافٍ وَابْدَأْ بِمَنْ تَعُولُ وَالْيَدُ الْعُلْيَا خَيْرٌ مِنَ الْيَدِ السُّفْلَى " .
