Either of the following can be used to clean in different situations: flowing water; well-water; spring water; rain water; stale water in a volume each of its sides being nearly three and a half feet; a small amount of water being poured on a filthy object sufficient to cleanse it; dust covered earth; direct sun-light; fire; change of state or form from one to another.

In several important traditions, the Prophet (Pbuh) has stressed on the value of purity and cleanliness in such a way that it seems to be one of the surprising Islamic issues to any intellectual. Cleanliness is half of faith. [Mizan al-Hikmat , v.5, p.558] The first thing that is considered in the Hereafter is cleanliness. [Ibid] The Prophet (Pbuh) was extremely sensitive to the issue of oral and dental hygiene, cleaning hair and face, clothes and furniture, lanes and streets and even the dead.

He was also superior to all in following hygienic rules and cleanliness. He ordered the dead to be washed with lotus and camphor water. Also he ordered that camphor be placed on the forehead where we prostrate to worship God. Also he ordered the grave to be dug deeper and to be careful in placing a stone above the head and a little bit distant from it, and to throw dust over the dead body in an orderly fashion.

Thus the body, the camphor and the dust will disintegrate and combine together in such a way as to maintain the health of citizens. These decrees are amazing ones and show the greatness of that noble Prophet's knowledge and wisdom. The Immaculate Imam Ali 's (Pbuh) knowledge and wisdom are manifestations of God's knowledge and wisdom.

The Prophet (Pbuh) was so pure and clean that Imam Ali (Pbuh) introduced him as the cleanest and the purest and asked all the people of the world to use the Prophet (Pbuh) as a model for cleanliness and purity of body and soul. Follow the example of your Prophet who is the cleanest and purest creature in existence. In fact, he is a model for anyone who wishes to follow him in all issues related to living.

[Nahj ul-Balaghah , Sermon 160] The Prophet (Pbuh) said: In fact God is pure, He likes the pure. He is clean, He likes the clean. [Mizan al-Hikmat , v.10, p.92] See how important cleaning is that there is a mention of it in God's presence. The Commander of the Faithful (Pbuh) said: Wash yourselves free of any bad, disturbing odors with water, and be responsible for yourself.
