Surely Allah has bought of the believers their persons and their property for this, that they shall have the garden; they fight in Allah's way, so they slay and are slain; a promise which is binding on Him in the Taurat and the Injeel and the Quran; and who is more faithful to his covenant than Allah? Rejoice therefore in the pledge which you have made; and that is the mighty achievement.

And if We had pleased We would certainly have given to every soul its guidance, but the word (which had gone forth) from Me was just: I will certainly fill hell with the jinn and men together.
