The Women - 4:112
Whoever commits a fault or a sin and then blames it on the innocent, he has certainly borne a great slander and a manifest sin.
The righteous remember God when they sin:
The Stories/28:16
"My Lord,"he said, "I have wronged myself, forgive me."And He forgave him. For He is Forgiving, Merciful."
The Stories/28:15
"He entered the city while his people were unaware. He saw two men fighting there, one from his side (Hebrew) and the other from the enemy´s side (Egyptian). The man from his side asked him for help against his enemy. So Moses struck the other with a blow and finished him off. He said, "This is the work of Satan; he is an enemy, a clear misleader."
The Heights/7:201
Whenever a dark suggestion from the devil reaches the righteous, they immediately remember. So they immediately see.
Prophet Hud/11:47
"He said: "My Lord, I seek refuge in You for supplicating to You about a matter of which I have no knowledge. If You do not forgive me and have mercy on me, I shall be of the losers."
The Heights/7:149
"When they regretted what they had done and realized that they had gone astray, they said: "If our Lord does not pity us and forgive us, we shall be losers"."
