Pride In Giving Charity
Sunan an-Nasai
أَخْبَرَنَا أَحْمَدُ بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنَا يَزِيدُ، قَالَ حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " كُلُوا وَتَصَدَّقُوا وَالْبَسُوا فِي غَيْرِ إِسْرَافٍ وَلاَ مَخِيلَةٍ " .
It was narrated from 'Amr bin Shu'aib, from his father, that his grandfather said: "Eat, give charity and clothe yourselves, without being extravagant, and without showing off."
