Amr bin Shu'ayb (may Allah have mercy on him) narrates from his father, and he from his grandfather, Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both), that the Messenger of Allah (peace and blessings be upon him) said: "What harm is there for any of you, when he intends to give something in charity, to make it on behalf of his parents? Then nothing at all will be reduced from their rewards."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Uthman bin Sa'd except Kharijah bin Mus'ab, and none from Kharijah except Ali bin al-Hasan, while Muhammad bin Abdullah bin Quhzadh is alone in narrating it."
