To je važno zbog toga što neki kritičari islama često tvrde da je Muhammed na svojim putovanjima morao vidjeti kršćanske i jevrejske svete knjige, i da je odatle posudio religijske ideje koje je preradio i širio kao poruku.
It is important because some critics of Islam have often claimed that Muhammad in his travels must have read Christian and Jewish scriptures, and so borrowed religious ideas from them which he then rehashed as his own message.
