Fath al-Rabbani

It is narrated from Sayyiduna Abdur Rahman bin Khabbab Salmi (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) intended to travel, he encouraged the people to help the army of hardship (Jaysh al-‘Usrah, referring to the expedition of Tabuk). Sayyiduna Uthman bin Affan (may Allah be pleased with him) said: I will give one hundred camels along with their saddles and the felt placed under the saddles. The Prophet (peace and blessings be upon him) further encouraged the people to help, and Sayyiduna Uthman (may Allah be pleased with him) again said: Another one hundred camels with their saddles and felts are upon me. After that, the Prophet (peace and blessings be upon him) descended one step from the pulpit and encouraged further, so Uthman bin Affan (may Allah be pleased with him) said: Another one hundred camels with their saddles and felts are upon me. I saw the Noble Prophet (peace and blessings be upon him) moving his hand in this manner. ‘Abd al-Samad (one of the narrators of the chain of transmission) extended his hand in the manner of a person extremely delighted. The Prophet (peace and blessings be upon him), while moving and shaking his hand in this way, said: After today, whatever Uthman does, there is no blame upon him.
