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 when those who believe in Our communications come to you, say: Peace be on you, your Lord has ordained mercy on Himself, (so) that if any one of you does evil in ignorance, then turns after that and acts aright, then He is Forgiving, Merciful.

Those whom the angels cause to die in a good state, saying: Peace be on you: enter the garden for what you did.

And when they hear idle talk they turn aside from it and say: We shall have our deeds and you shall have your deeds; peace be on you, we do not desire the ignorant.

And who speaks better than he who calls to Allah while he himself does good, and says: I am surely of those who submit?

And We have enjoined on man doing of good to his parents; with trouble did his mother bear him and with trouble did she bring him forth; and the bearing of him and the weaning of him was thirty months; until when he attains his maturity and reaches forty years, he says: My Lord! grant me that I may give thanks for Thy favor which Thou hast bestowed on me and on my parents, and that I may do good which pleases Thee and do good to me in respect of my offspring; surely I turn to Thee, and surely I am of those who submit.

The dwellers of the desert say: We believe. Say: You do not believe but say, We submit; and faith has not yet entered into your hearts; and if you obey Allah and His Messenger, He will not diminish aught of your deeds; surely Allah is Forgiving, Merciful.
