Swami-Vivekamanda said in 1890 in parlliament of world relision ; Mohamad was at higher stage relative to an ordinary man but he did,t know how he reached there .He him self accepted that a prophet came and took me in acave where I got knowledge. He did,t follow definite way (yoga;yam ,niyam ,aasan,Prnayam.... )like other great people so he had mixture of knowledge & blemishes . This mixture is now known as Koran .Vivekanand said thatit is clearely written in Koran that if you (muslims) love some one who does not bellong to your relision then try to convert his relision or kill him ....What a holy Koran..
