Hadith: If Allah wants to do good to a person

Razi Allah Anhu 

I heard Allah's Apostle

Peace Be Upon Him

saying, "If Allah wants to do good to a person, He makes him comprehend the religion. I am just a distributor, but the grant is from Allah. (And remember) that this nation (true Muslims) will keep on following Allah's teachings strictly and they will not be harmed by any one going on a different pathtill Allah's order (Day of Judgment) is established."
