It was narrated that Al-Ahnaf bin Qais said: "We set out for Hajj, and came to Al-Madinah intending to perform Hajj. While we were in our camping place unloading our mounts, someone came to us and said: The people have gathered in the Masjid and there is panic. So we set out and found the people gathered around a group in the middle of the Masjid, among whom were Ali, Az-Zubair, Talhah and Sad bin Abi Waqqas (RA). While we were like that, Uthman (RA) came, wearing a yellowish cloak with which he had covered his head. He said: Is Ali here? Is Talhah here? Is Az-Zubair here? Is Sad here? They said: Yes. He said: I adjure you by Allah, beside Whom there is none worthy of worship, are you aware that the Messenger of Allah (صلی اللہ علیہ و آلہ سلم) said: Whoever buys the Mirbad of Banu so and so, Allah will forgive him, and I bought it for twenty or twenty-five thousand, then I came to the Messenger of Allah (صلی اللہ علیہ و آلہ سلم) and told him, and he said: Add it to our Masjid and the reward for it will be yours? They said: By Allah, yes. He said: I adjure you by Allah, beside Whom there is none worthy of worship, are you aware that the Messenger of Allah (صلی اللہ علیہ و آلہ سلم) said: Whoever buys the well of Rumah, Allah will forgive him, so I bought it for such and such an amount, then I came to the Messenger of Allah (صلی اللہ علیہ و آلہ سلم) and told him, and he said: Give it to provide water for the Muslims, and the reward for it will be yours? They said: By Allah, yes. He said: I adjure you by Allah, beside Whom there is none worthy of worship, are you aware that the Messenger of Allah (صلی اللہ علیہ و آلہ سلم) said: Whoever equips these (men), Allah will forgive him, -meaning the army of Al-Usrah (i.e. Tabuk)- so I equipped them until they were not lacking even a rope or a bridle? They said: By Allah, yes. He said: O Allah, bear witness, O Allah, bear witness.
