We said to him ('Abdullah b. 'Umar): May Allah do good to you, these are desert Arabs and they are satisfied even with meagre (things). Thereupon Abdullah said: His father was loved dearly by 'Umar b. Khattib and I heard Messenger of Allah ﷺ as saying: The finest act of goodness on the part of a son is to treat kindly the loved ones of his father.  

أَنَّ رَجُلاً مِنَ الأَعْرَابِ لَقِيَهُ بِطَرِيقِ مَكَّةَ فَسَلَّمَ عَلَيْهِ عَبْدُ اللَّهِ وَحَمَلَهُ عَلَى حِمَارٍ كَانَ يَرْكَبُهُ وَأَعْطَاهُ عِمَامَةً كَانَتْ عَلَى رَأْسِهِ فَقَالَ ابْنُ دِينَارٍ فَقُلْنَا لَهُ أَصْلَحَكَ اللَّهُ إِنَّهُمُ الأَعْرَابُ وَإِنَّهُمْ يَرْضَوْنَ بِالْيَسِيرِ فَقَالَ عَبْدُ اللَّهِ إِنَّ أَبَا هَذَا كَانَ وُدًّا لِعُمَرَ بْنِ الْخَطَّابِ وَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ أَبَرَّ الْبِرِّ صِلَةُ الْوَلَدِ أَهْلَ وُدِّ أَبِيهِ  

The finest act of goodness is that a person should treat kindly the loved ones of his father.  

أَنَّ النَّبِيِّ ﷺ قَالَ أَبَرُّ الْبِرِّ أَنْ يَصِلَ الرَّجُلُ وُدَّ أَبِيهِ  

Arn't you so and so? He said: Yes He gave him his donkey and said: Ride it, and tie the turban round your head. Some of his companions said: May Allah pardon you, you gave to this desert Arab the donkey on which you enjoyed ride for diversion and the turban which you tied round your. head. Thereupon he said: Verily I heard Messenger of Allah ﷺ as saying: The finest act of goodness is the kind treatment of a person to the loved ones of his father after his death and the father of this person was a friend of 'Umar.  

أَنَّهُ كَانَ إِذَا خَرَجَ إِلَى مَكَّةَ كَانَ لَهُ حِمَارٌ يَتَرَوَّحُ عَلَيْهِ إِذَا مَلَّ رُكُوبَ الرَّاحِلَةِ وَعِمَامَةٌ يَشُدُّ بِهَا رَأْسَهُ فَبَيْنَا هُوَ يَوْمًا عَلَى ذَلِكَ الْحِمَارِ إِذْ مَرَّ بِهِ أَعْرَابِيٌّ فَقَالَ أَلَسْتَ ابْنَ فُلاَنِ بْنِ فُلاَنٍ قَالَ بَلَى فَأَعْطَاهُ الْحِمَارَ وَقَالَ ارْكَبْ هَذَا وَالْعِمَامَةَ قَالَ اشْدُدْ بِهَا رَأْسَكَ فَقَالَ لَهُ بَعْضُ أَصْحَابِهِ غَفَرَ اللَّهُ لَكَ أَعْطَيْتَ هَذَا الأَعْرَابِيَّ حِمَارًا كُنْتَ تَرَوَّحُ عَلَيْهِ وَعِمَامَةً كُنْتَ تَشُدُّ بِهَا رَأْسَكَ فَقَالَ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ مِنْ أَبَرِّ الْبِرِّ صِلَةَ الرَّجُلِ أَهْلَ وُدِّ أَبِيهِ بَعْدَ أَنْ يُوَلِّيَ وَإِنَّ أَبَاهُ كَانَ صَدِيقًا لِعُمَرَ
