O mankind! Fear your Lord! For the convulsion of the Hour(of Judgement) will be a thing terrible!
The Day ye shall see it, every mother giving suck shall forget her suckling babe, and every pregnant female shall drop her load(unformed): Thou shalt see mankind as in a drunken riot, yet not drunk: but dreadful will be the Wrath of Allah.[Qur'an 22:1-2]

Narrated Muawiya(RA): I heard Allah's Apostle(PBUH) 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 path till Allah's order (day of Judgment) is established."
