On the authority of Abu Malik al-Harith ibn 'Asim al-Ash'ari (may Allah be pleased with him) who said; The messenger of Allah (peace and blessings of Allah be upon him) said: "purity is half of faith. Alhamdu lillahi (praise be to Allah) fills the scales Subhanallah (how far is Allah from every imperfection) and Alhamdu lillahi (praise be to Allah) fill that which is between heaved and earth. Prayer is light; charity is a proof; patience is illumination; and the Qur'an is an argument for or against you. Everyone starts his day and is a vendor of his soul, either freeing it or bringing about its ruin."
