Musannaf Ibn Abi Shaybah 39356 — The acceptance of Islam by Uthman bin

Yazid bin Amr al-Ma'afiri said: I heard Abu Thawr al-Fahmi say: Sayyiduna Abd al-Rahman bin Udays al-Balawi (may Allah be pleased with him), who was among those who pledged allegiance to him (peace and blessings be upon him) under the tree, came to us. He ascended the pulpit, praised and glorified Allah Almighty, and then mentioned Sayyiduna Uthman (may Allah be pleased with him). Abu Thawr said: I went in to see Sayyiduna Uthman while he was under siege, and he said: I am the fourth to have accepted Islam.
