salam well wisher, it is really unfortunate that i provided you with tradition in history backed by hadith book references and yet you demand authenticity. brother, what more can i provide you with. this claim that history is filled with weak narration, well history gave the premise to hadith. ibn hisham, ibn saad were historians first them muhaddith. imam bukhari wrote history tarikh al kabir as well. the western world learnt history as a science from muslims and u feel history is inauthentic. what about the sirah of prophet(saw). it is history. then all sirah books be thrown into bins. history gave us the insight into origin of islam. hadith as a collection is history also. both follow the same science of narration. furthermore, hadith collection remains on fallacy more than history. here both hadith and history are in opposition to amir muawiya,s stands(ra) i hope the truth dawns on you brother.
