48:4It is He who sent down tranquility into the hearts of the believers, to add faith to their faith. To God belong the forces of the heavens and the earth. God is Knowing and Wise.

48:18God was pleased with the believers, when they pledged allegiance to you under the tree. He knew what was in their hearts, and sent down serenity upon them, and rewarded them with an imminent conquest.

48:26Those who disbelieved filled their hearts with rage—the rage of the days of ignorance. But God sent His serenity down upon His Messenger, and upon the believers, and imposed on them the words of righteousness—of which they were most worthy and deserving. God is aware of everything.
