Sahih Muslim · Book 45: The Book of Virtue, Enjoining Good Manners, and Joining of the Ties of Kinship · Upholding Ties Of Kinship, And The Prohibition Of Severing Them
Anas b. Malik reported that Allah's Messenger (ﷺ) said:
وَحَدَّثَنِي عَبْدُ الْمَلِكِ بْنُ شُعَيْبِ بْنِ اللَّيْثِ ، حَدَّثَنِي أَبِي ، عَنْ جَدِّي ، حَدَّثَنِي عُقَيْلُ بْنُ، خَالِدٍ قَالَ قَالَ ابْنُ شِهَابٍ أَخْبَرَنِي أَنَسُ بْنُ مَالِكٍ ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ أَحَبَّ أَنْ يُبْسَطَ لَهُ فِي رِزْقِهِ وَيُنْسَأَ لَهُ فِي أَثَرِهِ فَلْيَصِلْ رَحِمَهُ " .
He who likes that his sustenance should be expanded and his age may be lengthened should join the tie of kinship.
