Narrated Abu Huraira:
Allah's Apostle said, "Allah's Hand is full, and (its fullness) is not affected by the continuous spending, day and night." He also said, "Do you see what He has spent since He created the Heavens and the Earth? Yet all that has not decreased what is in His Hand." He also said, "His Throne is over the water and in His other Hand is the balance (of Justice) and He raises and lowers (whomever He will)." (See Hadith No. 206, Vol. 6)
