Anas reported the Messenger of Allah ﷺ 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 ﷺ
" مَنْ سَرَّهُ أَنْ يُبْسَطَ لَهُ فِي رِزْقِهِ وَيُنْسَأَ لَهُ فِي أَثَرِهِ فَلْيَصِلْ رَحِمَهُ " .
