Musnad Ahmad 26:252

'Abd al-Malik ibn 'Amr and Mu'ammal narrated to us, they said: Sufyan narrated to us, from Simak, from 'Abd al-Rahman, from 'Abdullah, who said: I arrived at the Prophet, peace and blessings of Allah be upon him, while he was in a red tent—'Abd al-Malik said: "made of leather"—among about forty men. He said: "You will be granted victories, you will be aided, and you will be successful. So whoever among you reaches that, let him fear Allah, enjoin the good, forbid the evil, and uphold the ties of kinship. Whoever lies about me intentionally, let him take his seat in the Fire. And the likeness of one who helps his people in something other than the truth is like a camel that falls into a well, and he is pulling it out by its tail."
