(22) بَابُ: {وَكَانَ عَرْشُهُ عَلَى الْمَاءِ}، {وَهُوَ رَبُّ الْعَرْشِ الْعَظِيمِ}
Narrated Abu Huraira:
The Prophet (ﷺ) said, "The Right (Hand) of Allah Is full, and (Its fullness) is not affected by the continuous spending night and day. 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 Right Hand. His Throne is over the water and in His other Hand is the Bounty or the Power to bring about death, and He raises some people and brings others down." (See Hadith No. 508)
