Surely, Allah has bought from the believers their souls and wealth in return for Paradise for them. (Now) they fight in the way of Allah. So they kill (for the Truth) and are slain (themselves too. Allah has taken) the firm promise as a bountiful obligation on Him in the Torah, the Gospel (the Injil) and the Qur’an. And who is truer to his promise than Allah? So, (believers,) rejoice over your bargain against which you have sold (your souls and wealth). This is but a colossal achievement.
