It is narrated from Sayyiduna Abd al-Rahman bin Samurah (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) was equipping Jaysh al-Usrah (the Army of Hardship, for the expedition of Tabuk), Sayyiduna Uthman (may Allah be pleased with him) came with a thousand dinars in his sleeve and poured them into the lap of the Messenger of Allah (peace and blessings be upon him). I saw the Messenger of Allah (peace and blessings be upon him) putting his blessed hand into the dinars, turning them over and saying: "Whatever Uthman bin Affan does after today will not harm him." He (peace and blessings be upon him) said this twice.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ibn Shawdhab except Damrah, and this hadith is narrated from Abd al-Rahman bin Samurah (may Allah be pleased with him) only with this chain."
