Believers! When you go forth in the way of Allah, discern (between friend and foe), and do not say to him who offers you the greeting of peace: 'You are not a believer.' If you seek the good of this worldly life, there lies with Allah abundant gain. After all, you too were such before, and then Allah was gracious to you. Discern, then, for Allah is well aware of what you do.
