Musannaf Ibn Abi Shayba 27:12

Malik ibn Isma'il narrated to us, from Mandil, from al-A'mash, from Mujahid, from 'Ubayd ibn 'Umayr, from Abu Dharr, who said: I went out in search of the Messenger of Allah (may Allah bless him and grant him peace), and I found him praying. I waited for him until he finished praying. He said: "I have been given tonight five things that no prophet before me was given: I have been aided by fear, so the enemy is struck with fear from a distance of a month's journey. I have been sent to the red and the black. The earth has been made for me a means of purification and a place of prayer. The spoils of war have been made lawful for me, and they were not made lawful for anyone before me. And it was said: 'Ask, and you shall be given.' So I have reserved it, and it will be attained by those among you who do not associate anything with Allah."
