Anas b. Malik reported: I heard Messenger of Allah ﷺ as saying: He who is desirous that his means of sustenance should be expanded for him or his age may be lengthened, should join the tie of relationship.

حَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى التُّجِيبِيُّ، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ " مَنْ سَرَّهُ أَنْ يُبْسَطَ عَلَيْهِ رِزْقُهُ أَوْ يُنْسَأَ فِي أَثَرِهِ فَلْيَصِلْ رَحِمَهُ " .
