And when it is said to them, Believe in what Allah has revealed, they say: We believe in that which was revealed to us; and they deny what is besides that, while it is the truth verifying that which they have. Say: Why then did you kill Allah's Prophets before if you were indeed believers?

Say: Whoever is the enemy of Jibreel-- for surely he revealed it to your heart by Allah's command, verifying that which is before it and guidance and good news for the believers.

Then after sorrow He sent down security upon you, a calm coming upon a party of you, and (there was) another party whom their own souls had rendered anxious; they entertained about Allah thoughts of ignorance quite unjustly, saying: We have no hand in the affair. Say: Surely the affair is wholly (in the hands) of Allah. They conceal within their souls what they would not reveal to you. They say: Had we any hand in the affair, we would not have been slain here. Say: Had you remained in your houses, those for whom slaughter was ordained would certainly have gone forth to the places where they would be slain, and that Allah might test what was in your breasts and that He might purge what was in your hearts; and Allah knows what is in the breasts.

When the disciples said: O Isa son of Marium! will your Lord consent to send down to us food from heaven? He said: Be careful of (your duty to) Allah if you are believers.

And whenever a chapter is revealed, saying: Believe in Allah and strive hard along with His Messenger, those having ampleness of means ask permission of you and say: Leave us (behind), that we may be with those who sit.

Or you should have a house of gold, or you should ascend into heaven, and we will not believe in your ascending until you bring down to us a book which we may read. Say: Glory be to my Lord; am I aught but a mortal messenger?
