Sahih al-Bukhari · Book 78: Good Manners and Form (Al-Adab) · Whoever was made wealthy because of keeping good relations with his kith and kin
Narrated Anas bin Malik:
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ ، حَدَّثَنَا اللَّيْثُ ، عَنْ عُقَيْلٍ ، عَنِ ابْنِ شِهَابٍ ، قَالَ 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 " .
Allah 's Apostle said, "Whoever loves that he be granted more wealth and that his lease of life be prolonged then he should keep good relations with his Kith and kin."
