It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "In the seven heavens there is not a place the size of a foot, a handspan or a palm except that in it there is an angel standing, or bowing, or prostrating. When the Day of Resurrection comes, they will all say together: Glory be to You! We have not worshipped You as You deserve to be worshipped, except that we did not associate anything with You."
