Know, may God help us and you with a spirit from Him, that since purity is cleanliness, we know that it is an attribute of purity, and it is moral and sensory, purity of the heart and purity of certain organs. So, the moral is the purity of the soul from immoral and reprehensible morals, the purity of the mind from the filth of thoughts and resemblance, the purity of the secret from looking at other people, and the purity of the organs. So know that for every A member of moral purity that we mentioned in the book Al-Tanzalat al-Mawsiliyya in the chapters on purification from it, and purity of the senses is one of the filthy things that souls naturally and usually filth, and these two purities are lawful .
