580. Narrated Aboo Huraira (radhi Allaahu anhu) : Allaah’s Messenger (Sallallaahu Alaihi Wasallam) said,
Allaah (Subhaanahu wata’alaa) said, ‘Spend (O man), and I shall spend on you.’ ” He also said, “Allaah’s Hand is full and (its fullness) is not affected by the continuous spending night and day.” He also said, “Do you see what He has spend since He created the heavens and the earth? Nevertheless, what is in His Hand is not decreased, and His Throne was on the water and in His Hand there is the balance (of justice), whereby He raises and lowers (people).
