I believe our prohet (pbuh) never compared Islam with other religion so as to abuse thier belief..I read when Omar (Ra) was reading other the religious scriptures of Jews our prophet was upset for he advised to follow Quran that was sent to him and his Ummah. Now to belittle once religion even if there is logic does not account for our Prophet's approach in understanding Islam.. I completely agree Dr.Naik to have knowledge of Islam..But inviting the people to Islam through humility and humbleness was why we have billions of followers of Islam around the world...The sahabas and ta'abaeen did not go and preach Islam in places like malaysia and indonesia with insults to their previous belief..The showed what Islam is though their acts of life not only through knowledge...
