Purification

Abu Malik at-Ash'ari reported:
The Messenger of Allah (ﷺ) 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.

It was narrated from Simak bin Harb, that Mus'ab bin Sa'd said:'" 'Abdullah bin 'Umar came to visit Ibn 'Amir  when he was sick and he said: 'Won't you supplicate to Allah for me, O  Ibn 'Umar ?' He said: 'I heard the Messenger of Allah (ﷺ) say: "No Salat  is accepted without Wudu' (purification), and no charity (is accepted)  that comes from Ghulul [1] " and you were the governor of Al-Basrah.' "  [1] Goods pilfered from the spoils of war prior to their authorized  distribution.
