An Imam of the Masjid-e-Shohda, Lahore is preaching on fridays that we have been studying wrong about the early life of Prophet Muhammad(P.B.U.H.) as after His Grand Father's death he was looked after by His father's elder brother Zubair Abu Tahir not as we are told since childhood that he was looked after by His uncle Abu Talib. The Imam says that these changes were made only to distract muslims from the true information. As his Uncle Tahir was a pious man and hated idol worship, Prophet Muhammad(P.B.U.H.) were brought up in his custody not under his Uncle Abu Talib who didn't leave his religion till the End. I am really confused and i am not getting any authentic resource about what this Imam is saying. If anyone have any information do share...
