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.

Know that this world's life is only sport and play and gaiety and boasting among yourselves, and a vying in the multiplication of wealth and children, like the rain, whose causing the vegetation to grow, pleases the husbandmen, then it withers away so that you will see it become yellow, then it becomes dried up and broken down; and in the hereafter is a severe chastisement and (also) forgiveness from Allah and (His) pleasure; and this world's life is naught but means of deception.
