Abu Hurairah reported,

From the Messenger of Allah ﷺ, several hadith were mentioned, among them that the Messenger of Allah ﷺ said, "Allah said to me, 'Spend, and I will spend on you.'"The Messenger of Allah ﷺ also said, "The right hand of Allah is full and overflowing, never diminished, pouring forth night and day. Have you considered what He has spent since He created the heavens and the earth? Yet what is in His right hand has not been diminished. His Throne is upon the water, and in His other hand is the grasp, raising and lowering."

Muslim 2309
