حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي يَعْقُوبَ الْكِرْمَانِيُّ، حَدَّثَنَا حَسَّانُ، حَدَّثَنَا يُونُسُ، حَدَّثَنَا مُحَمَّدٌ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَنْ سَرَّهُ أَنْ يُبْسَطَ لَهُ رِزْقُهُ أَوْ يُنْسَأَ لَهُ فِي أَثَرِهِ فَلْيَصِلْ رَحِمَهُ ".
Muhammad ibn Abi Yaqub al-Kirmani narrated to us: Hassan narrated to us: Yunus narrated to us: Muhammad narrated to us, from Anas ibn Malik, may Allah be pleased with him, who said: I heard the Messenger of Allah, peace and blessings be upon him, say: “Whoever would be pleased to have his provision expanded and his lifespan extended, let him maintain his ties of kinship.”
Translation notes
The Arabic idiom في أثره is rendered as an extension of lifespan.
