8:2The believers are those whose hearts tremble when God is mentioned, and when His revelations are recited to them, they strengthen them in faith, and upon their Lord they rely.

8:11He made drowsiness overcome you, as a security from Him. And He sent down upon you water from the sky, to cleanse you with it, and to rid you of Satan’s pollution, and to fortify your hearts, and to strengthen your foothold.

8:17It was not you who killed them, but it was God who killed them. And it was not you who launched when you launched, but it was God who launched. That He may bestow upon the believers an excellent reward. God is Hearing and Knowing.
