Muhammad bin Musa bin Muhammad al-Taymi narrates from his father that when the rout occurred in Tulayhah's army, Tulayhah fled to Syria. When he came back to Makkah during the caliphate of Sayyiduna Umar (may Allah be pleased with him), Sayyiduna Umar (may Allah be pleased with him) said: "O Tulayhah! You killed two righteous men, Ukkashah bin Mihsan and Thabit bin Aqram (may Allah be pleased with them both), so I do not love you." He replied: "O Umar! Allah honoured the two of them by my hands and spared me from being disgraced by their hands. Not all houses are built on love; but there is the handshake, which even two enemies exchange." After that Tulayhah (may Allah be pleased with him) became a good Muslim.
