Sahih Muslim 534
صحيح مسلم#534SahihAbu Malik at-Ash'ari reported:The Messenger of Allah (ﷺ) said: Cleanliness is half of faith and al-Hamdu Lillah (all praise and gratitude is for Allah alone) fills the scale, and Subhan Allah (Glory be to Allah) and al-Hamdu Lillah fill up what 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
