Ar-Rum [30:7] They know but the outer (things) in the life of this world: but of the End of things they are heedless.
Al-Hujraat [49:13] O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise each other). Verily the most honoured of you in the sight of Allah is (he who is) the most righteous of you. And Allah has full knowledge and is well acquainted (with all things).
Aal-e-Imran [3:144] Muhammad(saws) is no more than an Messenger: many were the Messengers that passed away before Him. If he died or was slain, will ye then turn back on your heels? If any did turn back on his heels, not the least harm will he do to Allah; but Allah (on the other hand) will swiftly reward those who (serve him) with gratitude.
