in Edition Clear Qur'an by Talal Itani / Aal-i-Imraan (The Family of Imraan)

3:135And those who, when they commit an indecency or wrong themselves, remember God and ask forgiveness for their sins—and who forgives sins except God? And they do not persist in their wrongdoing while they know.

3:154Then after the setback, He sent down security upon you. Slumber overcame some of you, while others cared only for themselves, thinking of God thoughts that were untrue—thoughts of ignorance—saying, “Is anything up to us?” Say, “Everything is up to God.” They conceal within themselves what they do not reveal to you. And they say, “If it was up to us, none of us would have been killed here.” Say, “Even if you Had stayed in your homes, those destined to be killed would have marched into their death beds.” God thus tests what is in your minds, and purifies what is in your hearts. God knows what the hearts contain.

3:191Those who remember God while standing, and sitting, and on their sides; and they reflect upon the creation of the heavens and the earth: “Our Lord, You did not create this in vain, glory to You, so protect us from the punishment of the Fire.”
