Sunan Abi Dawud, Hadith 1689

Anas reported the Messenger of Allah as saying : Anyone who is pleased that his sustenance is expanded and his age extended should do kindness to his near relatives.

حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، وَيَعْقُوبُ بْنُ كَعْبٍ، - وَهَذَا حَدِيثُهُ - قَالاَ حَدَّثَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي يُونُسُ، عَنِ الزُّهْرِيِّ، عَنْ أَنَسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَنْ سَرَّهُ أَنْ يُبْسَطَ لَهُ فِي رِزْقِهِ وَيُنْسَأَ لَهُ فِي أَثَرِهِ فَلْيَصِلْ رَحِمَهُ ‏" ‏ ‏.‏
