(9:111) God has purchased from those who acknowledge their very lives (Arab. أَنْفُسَهُمْ, anfusahum) and their wealth; that they will have the Garden. They fight in the cause of God so they kill and are killed. A promise that is true upon Him in the Torah, the Injeel and the Quran. Whoever fulfills his pledge to God, then have good news of the deal which you concluded with. Such is the supreme success.
(28:19) But when he intended to grip the one, who was their enemy, he said, "O Moses! Do you intend to kill me, as you killed a person (Arab. نَفْسًا, nafsan) yesterday? Obviously, you intend to be a despot on the Earth! And you do not intend to be among (self) improvers."
Those who forgot themselves
Signs within themselves
(41:53) We will show them Our signs in the horizons, and within themselves (Arab. أَنْفُسِهِمْ, anfusihim), until it becomes clear to them that this is the truth. Is it not enough that your Lord is witness over all things?
God prescribed mercy upon Himself
(6:12) Say, "To whom is all that is in heavens and earth?" Say, "To God." He has prescribed mercy upon Himself (Arab. نَفْسِهِ, nafsihi), that He will gather you to the day of Resurrection in which there is no doubt. Those who have lost themselves, they do not acknowledge.
(6:54) If those who acknowledge Our signs come to you, then say, "Peace be upon you, our Lord has prescribed mercy upon Himself (Arab. نَفْسِهِ, nafsihi), that any of you who commits sin out of ignorance and then repents afterwards and reforms, then He is Forgiving, Compassionate."
(3:93) All the food used to be lawful to the Children of Israel, except what Israel forbade for himself (Arab. نَفْسِهِ, nafsihi) before the Torah was sent down. Say, "Bring the Torah and recite it if you are truthful."
