Fiqh-us-Sunnah Volume 1, Purification and Prayer, Fiqh 1.063B.

This form of ablution is viewed as a blessing from Allah to the Muslims. Jabir relates that the Prophet, upon whom be peace, said, “I have been given five things that were not given to anyone before me: I have been made victorious due to fear for a distance of one month’s journey; the earth has been made a place of prayer for me; wherever and whoever of my nation wants to pray, he may pray; and the war booty has been made lawful for me, and this was not lawful for anyone before me. I have been given permission to intercede. The prophets used to be raised for their own people only, but I have been raised for all of mankind.” (Related by al-Bukhari and Muslim.)
