One of the finest acts of kindness is for a man to treat his father’s friends in a kindly way after he has departed.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ أَبَرَّ الْبِرِّ صِلَةُ الْمَرْءِ أَهْلَ وُدِّ أَبِيهِ بَعْدَ أَنْ يُوَلِّيَ  

the Prophet said: "Among the most dutiful of deeds is that a man nurture relations with the people his father was friends with."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ أَبَرَّ الْبِرِّ أَنْ يَصِلَ الرَّجُلُ أَهْلَ وُدِّ أَبِيهِ قَالَ وَفِي الْبَابِ عَنْ أَبِي أَسِيدٍ  

[Machine] From the Messenger of Allahﷺ that he said: "Indeed, the best form of righteousness is for a man to maintain good relations with the loved ones of his father."  

عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ قَالَ إِنَّ أَبَرَّ الْبِرِّ أَنْ يَصِلَ الرَّجُلُ أَهْلَ وُدِّ أَبِيهِ  

the Prophet said: "Among the most dutiful of deeds is that a man nurture relations with the people his father was friends with." (Using translation from Tirmidhī 1903)   

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «إِنَّ أَبَرَّ الْبِرِّ أَنْ يَصِلَ الرَّجُلُ أَهْلَ وُدِّ أَبِيهِ»  

[Machine] The Messenger of Allah (peace and blessings be upon him) said: "The best righteousness is that a person maintains ties with his family even after they have cut off relations with him."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «إِنَّ أَبَرَّ الْبِرِّ أَنْ يَصِلَ الرَّجُلُ أَهْلَ وُدِّ أَبِيهِ بَعْدَ أَنْ يُوَلِّيَ»  

"إِنَّ أبَّر البِرِّ أن يَصِلَ الرَّجُلُ أهلَ وُدِّ أبِيهِ بعدَ أن يُولِّى الأَبُ ".  

"إِنَّ من برِّ الرَّجُل بأَبيه أن يَبرَّ أَهلَ وُدِّ أَبيه".
