Abdullah bin Dinar (may Allah have mercy on him) says that once a Bedouin passed by Sayyiduna Ibn Umar (may Allah be pleased with them both), who was going for Hajj. Sayyiduna Ibn Umar (may Allah be pleased with them both) asked the Bedouin, "Are you not so-and-so, son of so-and-so?" He replied, "Yes, indeed." Sayyiduna Ibn Umar (may Allah be pleased with them both) went to his donkey, which he used to rest on when he became tired of riding, and took his turban, with which he used to tie his head, and gave both of these things to the Bedouin. When he left, one of us asked him, "You gave your donkey, on which you used to rest, and the turban, which you used to tie on your head, to this Bedouin, whereas he would have been pleased even with a single dirham?" Sayyiduna Ibn Umar (may Allah be pleased with them both) replied: "I heard the Prophet (peace and blessings be upon him) say that the greatest act of goodness is that a person maintains ties with his father's friends after his father has passed away."
