Musannaf Ibn Abi Shayba 33:1075

Al-Fadl ibn Dukayn narrated to us, he said: Al-A’mash narrated to us, from ‘Amr ibn Murrah, from a sheikh who was called Abu Yazid, he said: I heard ‘Abdullah ibn ‘Amr saying: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever lets the people hear of his deed, Allah will let the listeners of His creation hear of him on the Day of Resurrection, and He will belittle him and make him small."
