Peace be upon him

Peace Be Upon Him – in Arabic: صلى الله عليه وسلم; salla Allahu alayhi wa sallam, also transliterated as sallalahu aleyhi wasallam – is a phrase that Muslims often say after mentioning the name of the Prophet Muhammad. An alternative translation is "May God bless him and grant him peace". In Arabic, these greetings are called salawat.

For the other prophets and the angels, a more abbreviated form with basically the same meaning, alayhi is-salaam (Arabic: عليه السلام) is often used.

It is seen as a mark of respect and is related to the Islamic concept of dhikr or remembrance. In English writing it is generally abbreviated as PBUH or SAW.
