asalam aleikum
all the prophets are equal and in the last 2 ayahs of suratul Baqara Allah defines the muslim as the one who makes no distinction and that is why after we mention any prophet we have to say peace and blessings on them and SAW can be used for the other prophets just as ASW can be used for Prophet Muhammed, but as the prophet was sent to the whole of mankind he is different form the other prophets who were sent to their people, the Prophet Muhammeds miracle is the living miracle which we read and contemplate upon everyday so we are closer to him.
he is the only prophet whose entire life is known, his Seerah is known his personal, military life is documented, he exists in history as a living part of history.
however i have always wondered why some muslims act like all the other prophets are irrelevant, only Allah can differntiate between the prophets i dont believe we should say one is greater unless Allah himself has said so even the prophet himself forbade his companions from saying he was better than Moses (ASW) saying on the day of Qiyamah when he raises before any other person he will see Moses(asw) already risen, and there are similar hadith about the prophets so lets follow his sunnah and not raise him up like the xtians have raised up their prophets
