A man came to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) and asked him (for something), so he threw his turban to him. Someone among those present said to him: "If you had given him a dirham, it would have been enough." Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "I heard the Messenger of Allah (peace and blessings be upon him) say: 'Part of righteousness is that a man keeps ties with and treats well his father's friend.' And this man was a friend of (my father) Sayyiduna Umar (may Allah be pleased with him)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Wasim bin Jamil except Qutaybah."
