Mukhtasar Muslim (Abridged) 510 — Supplicating for one who brings

Sayyiduna Abdullah bin Abi Awfa (may Allah be pleased with him) says that it was the blessed habit of the Messenger of Allah (peace and blessings be upon him) that when any people brought charity, he (peace and blessings be upon him) would supplicate for them, saying: O Allah! Have mercy on them. Then my father Abu Awfa (may Allah be pleased with him) brought charity, so the Prophet (peace and blessings be upon him) said: O Allah! Have mercy on the family of Abu Awfa.
