It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "I have been given five things that were not given to any prophet before me: I have been sent to the red and the black (people of every colour and race), whereas the prophets before were sent only to their own particular people; I have been aided by awe, so that the enemy fears me even at a distance of a month or two months' journey; the spoils of war have been made lawful for me, while they were not lawful for anyone before me; the whole earth has been made for me a place of prostration and a means of purification; and it was said to me: 'Ask, and you will be given.' So I have saved my supplication as intercession for my Ummah, and it will reach, if Allah wills, everyone who died without associating anything with Allah."
