Sahih Muslim, Chapter: Purification (Kitab Al-Taharah)

The Messenger of Allah (may peace be upon him) said: Cleanliness is half of faith and al-’Hamdu Liliah (Praise be to Allah) fills the scale, and Subhan Allah (Glory be to Allah) and al-’Hamdu Liliah (Praise be to Allah) fill upwhat is between the heavens and the earth, and prayer is a light, and charity is proof (of one's faith) and endurance is a brightness and the Holy Qur'an is a proof on your behalf or against you. All men go out early in the morning and sell themselves, thereby setting themselves free or destroying themselves.
