Sayyiduna Abd al-Rahman bin Jannab (may Allah be pleased with him) said: "I was present when the Prophet (peace and blessings be upon him) urged (the people) to support the Army of Hardship (the army of the expedition of Tabuk). Then Sayyiduna Uthman bin Affan (may Allah be pleased with him) stood up and said: 'O Messenger of Allah, I pledge a hundred camels, with their saddle-cloths and saddles, in the path of Allah.' Then I myself saw and heard the Messenger of Allah (peace and blessings be upon him) on the pulpit, saying: 'Whatever Uthman does after this, there is no blame upon him.'"
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Abd al-Rahman bin Jannab (may Allah be pleased with him) only with this chain; Sakan bin al-Mughirah is alone in it."
