Peace be upon him (Islam)
alayhi as-salām (AAS) is a phrase Muslims say whenever they refer to the name of any prophet, messenger, and chosen figure of God. "Peace be upon him" is the English-language translation of alayhi as-salām. The phrase is used in Islamic practice to show respect. Muslims say or write the phrase to get Allah's blessings for the prophet/messenger, and in turn, get blessings for themselves. The abbreviations PBUH and AAS are used in writing in the Muslim world in private and sometimes government documents. The Qur'an, the holy book of Islam, says this respect must be given.
