Ali bin Abu Talib reported,

He said, when the Messenger of Allah ﷺ raised his head from bowing, he would say, "Allah hears whoever praises Him. Our Lord, to You belongs all praise, filling the heavens, filling the earth, filling whatever lies between them, and filling whatever else You will beyond that."
