Surah Hud [11:47] - Bismillahir Rahmahir Raheem
Rabbi innee aAAoothu bikaan as-alaka ma laysa lee bihi AAilmun wa-illataghfir lee watarhamnee akun mina alkhasireen = My Lord, I seek refuge in You from asking that of which I have no knowledge. And unless You forgive me and have mercy upon me, I will be among the losers.
I have gotten interest on the topic if Imam Al Mahdi and see there are unclear things in the story. I believe a certain part was hidden from us, for the safety of his lineage, and place.
Narju Khatun said, "may the offspring of your prophet dispbell your doubts". What does this mean people? Could it mean that something will happen to the offspring of the prophet Muhammad ((صلى الله عليه وآله وسلم))? Hassan Al askari is the 11th imam, he was friends with muslims, jews and christians of Baghdad. Narjis Khatun went to Baghdad. Here the child they recieved i believe is the holder of the lineage of Muhammad ((صلى الله عليه وآله وسلم)) through Al Askari. This child i belive becuse it was ordained by God, was hidden amongst the jews of Bahgdad in order to secure its safety. All the previous Imams where killed. So in order to save the lineage of Muhammad ((صلى الله عليه وآله وسلم)) through the 12th imams i believe they hid him amongst the jews. (They follow kosher wery strict which is bacially halal lifestyle). There he grew up, got children and the lineage survived until when the time comes, Imam mahdi will be a person growing up jewish, but be guided to Islam. This also means some jews today are AhlulBayt, and is a way to ensure peace amongst the nations who recieved revelation.
Could this be?
