On the authority of Abu Malik al-Harith bin Asim al-Ashari (may Allah be pleased with him) who said: The Messenger of Allah (peace be upon him) said:
"Purity is half of Iman. Alhamdulillah (praise be to Allah) fills the scales, and subhan-Allah (how far from imperfection is Allah) and Alhamdulillah (praise be to Allah) fill that which is between heaven and earth. And the Salah (prayer) is a light, and charity is a proof, and patience is illumination, and the Qur'an is a proof either for you or against you. Every person starts his day as a vendor of his soul, either freeing it or bringing about its ruin."
