I heard Messenger of Allah ﷺ saying, "Who ever is pleased that he be granted more wealth and that his lease of life be pro longed, then he should keep good relations with his Kith and kin."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ سَرَّهُ أَنْ يُبْسَطَ لَهُ فِي رِزْقِهِ وَأَنْ يُنْسَأَ 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."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ أَحَبَّ أَنْ يُبْسَطَ لَهُ فِي رِزْقِهِ وَيُنْسَأَ لَهُ فِي أَثَرِهِ فَلْيَصِلْ رَحِمَهُ
