Tayammum (Dry Purification)

Tayammum is the divinely permitted substitute for wudu and ghusl when water is unavailable or its use is harmful. It is performed using pure earth — soil, sand, stone, or any substance of the same category — and is a concession (rukhsah) that demonstrates the ease and mercy inherent in Islamic law. Allah Most High says: "And if you are ill or on a journey, or one of you comes from the place of relieving himself, or you have contacted women and do not find water, then seek clean earth and wipe over your faces and your hands with it" (al-Ma'idah 5:6).

Conditions for the Validity of Tayammum: Several conditions must be present. First, there must be a legitimate reason permitting tayammum: absence of water after a genuine search, or the presence of water that one is unable to use due to illness such that using water would cause harm or significantly delay recovery, or cold so extreme that using water poses a risk of harm with no means of warming it. Second, the time of prayer must have entered, because tayammum is time-specific in the Hanbali view — it cannot be performed in advance. Third, the earth used must be pure. Fourth, the intention to perform tayammum must be present.

How Tayammum is Performed: The person strikes the earth once with both palms, then wipes the entire face with the inner surfaces of the fingers, then wipes the back of the right hand with the left palm and vice versa. The Hanbali school holds that a single strike of the earth is sufficient for both the face and the hands. Some scholars require the arms up to the wrist rather than the full forearm, and this is the more correct view based on the relevant hadiths, including the hadith of Ammar ibn Yasir (Bukhari and Muslim) who described the Prophet teaching tayammum as a single strike covering the face and hands.

What Tayammum Permits: Tayammum performed for minor impurity (hadath asghar) permits everything that wudu permits. Tayammum for major impurity (hadath akbar, i.e., janabah) permits everything that ghusl permits. Each tayammum is valid for one prayer in the Hanbali school, though some scholars hold it valid for multiple prayers as long as the time remains, and this latter view has evidential support.

What Nullifies Tayammum: Tayammum is nullified by everything that nullifies wudu, and additionally by the discovery or ability to use water, and by the end of the time for which it was performed according to the Hanbali view.
