And if he be a liar, on him is (the sin of) his lie; but; if he is telling the Truth, then will fall on you something of the (calamity) of which he warns you: truly Allah does not guide one who transgresses and lies! [Qur'an 40:28]

Those truly fear Allah, among His servants, who have knowledge: for Allah is exalted in Might, Oft-Forgiving. [Qur'an 35:27-28]
And among His Signs are the ships, smooth-running through the ocean, (tall) as mountains. [Qur'an 42:32]
