Qur'an, Al-Baqara, Surah 2:255
There is no god but God, who lives eternally. Neither slumber nor sleep overtakes him. To him belongs everything in the heavens and on the earth. Who can intercede with him, except by his permission? He knows what lies before and behind all people. Human beings can only understand those parts of his truth which he wishes them to understand. His throne is as vast as the sky and the earth; and sustaining both the sky and the earth does not weary him. He is the highest and the greatest.
