TS, please correct your knowledge, Imam Mahdi is not Messiah, Nabi Isa is not Jesus, Nabi Musa is not Moses, Malaikat Jibrail is not Gabriel. There is no such thing as a.k.a when it comes to Muslim Prophet and Malaikat, the name is exact and should not be change. Same like Nabi Muhammad, there is no other name for Nabi Muhammad. So do not confuse others with your cut-and-paste knowledge.
