Musnad Ahmad 15860 — Hadith of Ma'n ibn Yazid al-Sulami

It is narrated from Sayyiduna Ma'n bin Yazid that I, my father, and my grandfather pledged allegiance to the Prophet (ﷺ). Then the Prophet (ﷺ) delivered the sermon for my marriage proposal and married me. My father Yazid took out some dinars with the intention of giving charity and placed them in the hand of a man in the mosque. That man was me. I took those dinars and came to him, so he said, "I did not intend to give these dinars to you." I brought this case to the Prophet (ﷺ), so the Prophet (ﷺ) said: "Yazid, you have received the reward of your intention, and Ma'n, what has come into your hand is yours."
