'Peace be upon him' (said of the prophets) Purdah covering all but eyes, hands and feet
Means "peace be upon him". Used within Islam when referring to prophets. We do not use this term when referring to Hazrat Isa al Masih (Jesus), however, because the Bible teaches that Jesus is the Prince of Peace, the one who ushered in a Kingdom of Peace upon the earth. This phrase also means "May our (and possibly God's) peace be accorded to him." It is Hazrat Isa who grants us peace, not we who can grant Him peace.
When Muslims take the name of a Messenger in writing, they usually add the salutation PBUH(Peace Be Upon Him). This salutation is not used in the Quran. It should be implicitly understood that, as mentioned in Sura As-Saaffaat (The Ranks) (37:181), we do convey Peace upon all the Messengers of Allah, and Praise be to Allah, Sustainer of the Universe.
