On the authority of Abu Malik al-Harith bin ’Asim al-Ash’ari, radiyallahu ’anhu, who said: The Messenger of Allah, sallallahu ’alayhi wasallam, said: \”Purification is half of iman (faith). Saying ’Al-Hamdulillah’ (Praise be to Allah) fills the scales. Saying ’Subhanallah wa al-Hamdulillahi’ (Exhalted be Allah and Praise be to Allah) fills the space between the heavens and the earth. Salah (prayer) is a light. Sadaqah (charity) is a proof. Sabr (patience) is a shining glory. The Qur’an is an argument either for you or against you. Everybody goes out in the morning and sell themselves, thereby setting themselves free or destroying themselves.\” [Muslim]
