Abu Hurairah reported,

The Messenger of Allah ﷺ said that Allah said, "Spend, and I will spend on you."He also said, "The hand of Allah is full. No expenditure diminishes it, pouring forth night and day."And he said, "Have you considered all that He has spent since He created the heavens and the earth? It has not diminished what is in His hand. His Throne was upon the water, and in His hand is the Scale, which He lowers and raises."

عن أبي هريرة

أن رسول الله ﷺ قال: قال الله عز وجل: أنفق أنفق عليك. وقال: يد الله ملأى لا تغيضها نفقة سحاء الليل والنهار. وقال: أرأيتم ما أنفق منذ خلق السماء والأرض فإنه لم يغض ما في يده، وكان عرشه على الماء، وبيده الميزان يخفض ويرفع.
