Sahih Muslim, 6513

Ibn Dinar reported that a desert Arab met Abdullah b. 'Umar on the way to Mecca. 'Abdullah greeted him and mounted him upon the donkey on which he had been riding and gave him the turban that he had on his head. Ibn Dinar (further) reported: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 Allah's Messenger (ﷺ) as saying: The finest act of goodness on the part of a son is to treat kindly the loved ones of his father

Rapporté par Ibn Dinar رضي الله عنه : « Un Bédouin a rencontré Abdullah b. 'Umar sur la route de La Mecque. ‘Abdullah le salua, le fit monter sur l’âne qu’il montait et lui donna le turban qu’il portait sur la tête. Ibn Dinar a raconté : Nous lui avons dit : “Qu’Allah te fasse du bien ! Ce sont des Bédouins, ils se contentent de peu.” Abdullah répondit : “Son père était très cher à ‘Umar b. Khattab, et j’ai entendu le Messager d’Allah ﷺ dire : ‘Le meilleur acte de bonté d’un fils est de bien traiter les amis de son père.’” »
