The Book of Prayers (Kitab Al-Salat)
Muslim :: Book 4 : Hadith 1058
Jabir b. 'Abdullah al-Ansari reported: The Prophet (may peace be upon him) said: I have been conferred upon five (things) which were not granted to anyone before me (and these are): Every apostle wassent particularly to his own people, whereas I have been sent to all the red and the black the spoils of war have been made lawful for me, and these were never made lawful to anyone before me, and the earth has been made sacred and pure and mosque for me, so whenever the time of prayer comes for any one of you he should pray whenever he is, and I have been supported by awe (by which the enemy is overwhelmed) from the distance (which one takes) one month to cover and I have been granted intercession.
