Musnad Ahmad 769:9

Waki' narrated to us, Sufyan narrated to us, from Yazid Abu Khalid al-Dalani, from Ibrahim al-Saksaki, from Ibn Abi Awfa, who said: A man came to the Prophet, peace and blessings of Allah be upon him, and said: "O Messenger of Allah, I cannot learn anything from the Quran, so teach me what will suffice me." He said: "Say: 'Subhan Allah (Glory be to Allah), wal-hamdu lillah (and praise be to Allah), wa la ilaha illallah (and there is no god but Allah), wallahu akbar (and Allah is the Greatest), wa la hawla wa la quwwata illa billah (and there is no power nor strength except by Allah).'" The man said: "O Messenger of Allah, this is for Allah, the Mighty and Majestic, so what is for me?" He said: "Say: 'Allahummaghfir li (O Allah, forgive me), warhamni (and have mercy on me), wa 'afini (and grant me well-being), wahdini (and guide me), warzuqni (and provide for me).'" Then he turned away, holding his hands together. The Prophet, peace and blessings of Allah be upon him, said: "As for this one, he has filled his hands with good." Mis'ar said: I heard this hadith from Ibrahim al-Saksaki, from Ibn Abi Awfa, from the Prophet, peace and blessings of Allah be upon him, and others confirmed it for me.
