Surely Allah is not ashamed to set forth any parable-- (that of) a gnat or any thing above that; then as for those who believe, they know that it is the truth from their Lord, and as for those who disbelieve, they say: What is it that Allah means by this parable: He causes many to err by it and many He leads aright by it! but He does not cause to err by it (any) except the transgressors,

Have you not considered him (Namrud) who disputed with Ibrahim about his Lord, because Allah had given him the kingdom? When Ibrahim said: My Lord is He who gives life and causes to die, he said: I give life and cause death. Ibrahim said: So surely Allah causes the sun to rise from the east, then make it rise from the west; thus he who disbelieved was confounded; and Allah does not guide aright the unjust people.

O you who believe! be not like those who disbelieve and say of their brethren when they travel in the earth or engage in fighting: Had they been with us, they would not have died and they would not have been slain; so Allah makes this to be an intense regret in their hearts; and Allah gives life and causes death and Allah sees what you do.

And he said: You have only taken for yourselves idols besides Allah by way of friendship between you in this world's life, then on the resurrection day some of you shall deny others, and some of you shall curse others, and your abode is the fire, and you shall not have any helpers.
