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,

And when Ibrahim said: My Lord! show me how Thou givest life to the dead, He said: What! and do you not believe? He said: Yes, but that my heart may be at ease. He said: Then take four of the birds, then train them to follow you, then place on every mountain a part of them, then call them, they will come to you flying; and know that Allah is Mighty, Wise.

And (make him) a messenger to the children of Israel: That I have come to you with a sign from your Lord, that I determine for you out of dust like the form of a bird, then I breathe into it and it becomes a bird with Allah's permission and I heal the blind and the leprous, and bring the dead to life with Allah's permission and I inform you of what you should eat and what you should store in your houses; most surely there is a sign in this for you, if you are believers.

And Musa said: Our Lord! surely Thou hast given to Firon and his chiefs finery and riches in this world's life, to this end, our Lord, that they lead (people) astray from Thy way: Our Lord! destroy their riches and harden their hearts so that they believe not until they see the painful punishment.

And those who believe and do good are made to enter gardens, beneath which rivers flow, to abide in them by their Lord's permission; their greeting therein is, Peace.

So whatever thing you are given, that is only a provision of this world's life, and what is with Allah is better and more lasting for those who believe and rely on their Lord.
