Mukhtasar Bukhari

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "Allah the Exalted says: Spend, I will spend on you (I will give you)." And he, peace and blessings be upon him, said: "Allah's hand is full; spending during the night and day does not diminish it. Do you not see how much He has spent since He created the heavens and the earth? Yet what is in His hand (treasure) has not decreased at all. And (before the creation of the heavens and the earth) Allah's Throne was upon water, and in His hand is the balance (of justice), which He lowers for whom He wills and raises for whom He wills (increases or decreases sustenance)."
