The Messenger of Allah (pbuh) said: 'Cleanliness is half of faith, and [saying] 'Praise be to God' fills the scale, and [saying] 'Glory be to God' and 'Praise be to God' fill up what is between the heavens and the earth, and prayer is a light, and charity is proof [of one's faith], and patience is a brightness, and the Qur'an is a proof for or against you. All men go out early in the morning and sell themselves, some setting themselves free and others destroying themselves.'(Narrated by Muslim)
(6:59) He has the keys to the realm that lies beyond the reach of human perception; none knows them but He. And He knows what is on the land and in the sea; there is not a leaf which falls that He does not know about and there is not a grain in the darkness of the earth or anything green or dry which has not been recorded in a Clear Book.
