Surely those who have bought unbelief at the price of faith shall do no harm at all to Allah, and they shall have a painful chastisement.

And most surely of the followers of the Book there are those who believe in Allah and (in) that which has been revealed to you and (in) that which has been revealed to them, being lowly before Allah; they do not take a small price for the communications of Allah; these it is that have their reward with their Lord; surely Allah is quick in reckoning.

O you who believe! call to witness between you when death draws nigh to one of you, at the time of making the will, two just persons from among you, or two others from among others than you, if you are travelling in the land and the calamity of death befalls you; the two (witnesses) you should detain after the prayer; then if you doubt (them), they shall both swear by Allah, (saying): We will not take for it a price, though there be a relative, and we will not hide the testimony of Allah for then certainly we should be among the sinners.

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.
