Maintaining what was loved by ones father

'Abdullah ibn Dinar reported that Ibn 'Umar passed by a bedouin during a journey. The bedouin's father had been a friend of 'Umar's. The bedouin said, "Am I not the son of so-and-so?" He said, "Yes, indeed." Ibn 'Umar ordered that he be given a donkey which was following him. He also took off his turban and gave it to him, One of the men with him said, "Wouldn't two dirhams be enough for him?" He replied, "The Prophet ﷺ said, 'Maintain what your father loved. Do not cut it off so that Allah puts out your light."

مَرَّ أَعْرَابِيٌّ فِي سَفَرٍ فَكَانَ أَبُو الأعْرَابِيِّ صَدِيقًا لِعُمَرَ رَضِيَ اللَّهُ عَنْهُ فَقَالَ لِلأَعْرَابِيِّ أَلَسْتَ ابْنَ فُلاَنٍ؟ قَالَ بَلَى فَأَمَرَ لَهُ ابْنُ عُمَرَ بِحِمَارٍ كَانَ يَسْتَعْقِبُ وَنَزَعَ عِمَامَتَهُ عَنْ رَأْسِهِ فَأَعْطَاهُ فَقَالَ بَعْضُ مَنْ مَعَهُ أَمَا يَكْفِيهِ دِرْهَمَانِ؟ فَقَالَ قَالَ النَّبِيُّ ﷺ احْفَظْ وُدَّ أَبِيكَ لاَ تَقْطَعْهُ فَيُطْفِئَ اللَّهُ نُورَكَ
