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 leave those who have taken their religion for a play and an idle sport, and whom this world's life has deceived, and remind (them) thereby lest a soul should be given up to destruction for what it has earned; it shall not have besides Allah any guardian nor an intercessor, and if it should seek to give every compensation, it shall not be accepted from it; these are they who shall be given up to destruction for what they earned; they shall have a drink of boiling water and a painful chastisement because they disbelieved.

There is no blame on the blind man, nor is there blame on the lame, nor is there blame on the sick, nor on yourselves that you eat from your houses, or your fathers' houses or your mothers' houses, or your brothers' houses, or your sisters' houses, or your paternal uncles' houses, or your paternal aunts' houses, or your maternal uncles' houses, or your maternal aunts' houses, or what you possess the keys of, or your friends' (houses). It is no sin in you that you eat together or separately. So when you enter houses, greet your people with a salutation from Allah, blessed (and) goodly; thus does Allah make clear to you the communications that you may understand.
