O you who believe! do not make your charity worthless by reproach and injury, like him who spends his property to be seen of men and does not believe in Allah and the last day; so his parable is as the parable of a smooth rock with earth upon it, then a heavy rain falls upon it, so it leaves it bare; they shall not be able to gain anything of what they have earned; and Allah does not guide the unbelieving people.

And those who disbelieve say: Why is not a sign sent down upon him by his Lord? Say: Surely Allah makes him who will go astray, and guides to Himself those who turn (to Him).

And even if there were a Quran with which the mountains were made to pass away, or the earth were travelled over with it, or the dead were made to speak thereby; nay! the commandment is wholly Allah's, Have not yet those who believe known that if Allah please He would certainly guide all the people? And (as for) those who disbelieve, there will not cease to afflict them because of what they do a repelling calamity, or it will alight close by their abodes, until the promise of Allah comes about; surely Allah will not fail in (His) promise.

Surely those who disbelieve and turn away from Allah's way and oppose the Messenger after that guidance has become clear to them cannot harm Allah in any way, and He will make null their deeds.

It is they who disbelieved and turned you away from the Sacred Mosque and (turned off) the offering withheld from arriving at its destined place; and were it not for the believing men and the believing women, whom, not having known, you might have trodden down, and thus something hateful might have afflicted you on their account without knowledge-- so that Allah may cause to enter into His mercy whomsoever He pleases; had they been widely separated one from another, We would surely have punished those who disbelieved from among them with a painful punishment.

And We have not made the wardens of the fire others than angels, and We have not made their number but as a trial for those who disbelieve, that those who have been given the book may be certain and those who believe may increase in faith, and those who have been given the book and the believers may not doubt, and that those in whose hearts is a disease and the unbelievers may say: What does Allah mean by this parable? Thus does Allah make err whom He pleases, and He guides whom He pleases, and none knows the hosts of your Lord but He Himself; and this is naught but a reminder to the mortals.
