Sunan an-Nasa'i 2559
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."
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 ‏"‏ ‏.‏
