O you who believe! when you go to war in Allah's way, make investigation, and do not say to any one who offers you peace: You are not a believer. Do you seek goods of this world's life! But with Allah there are abundant gains; you too were such before, then Allah conferred a benefit on you; therefore make investigation; surely Allah is aware of what you do.

And strive hard in (the way of) Allah, (such) a striving a is due to Him; He has chosen you and has not laid upon you an hardship in religion; the faith of your father Ibrahim; He named you Muslims before and in this, that the Messenger may be a bearer of witness to you, and you may be bearers of witness to the people; therefore keep up prayer and pay the poor-rate and hold fast by Allah; He is your Guardian; how excellent the Guardian and how excellent the Helper!

Say to those of the dwellers of the desert who were left behind: You shall soon be invited (to fight) against a people possessing mighty prowess; you will fight against them until they submit; then if you obey, Allah will grant you a good reward; and if you turn back as you turned back before, He will punish you with a painful punishment.
