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 what He has spent since He created the heavens and the earth? Yet that has not decreased what is in His hand. His Throne is 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.
