In the Quran

(2:248) Their prophet said to them, "The sign of his kingship shall be that he brings to you the ark in which there is tranquility (Arab. سَكِينَةٌ, sakīnatun) from your Lord and the legacy of what was left behind by the descendants of Moses and the descendants of Aaron being carried by the angels. In this is a sign for you if you acknowledge."

(48:18) God is pleased with those who acknowledge who pledged allegiance to you under the tree. He thus knew what was in their hearts, so He sent down the Tranquility (Arab. السَّكِينَةَ, l-sakīnata) upon them, and rewarded them with a near victory.

(48:4) He is the One who sends down the Tranquility (Arab. السَّكِينَةَ, l-sakīnata) into the hearts of those who acknowledge, so that they may increase in acknowledgement along with their present acknowledgement. To God belongs the soldiers of the heavens and the earth, and God is knowledgeable, wise.
