What tayammum is
Tayammum (تَيَمُّم) is the purification substitute for both wudhu and ghusl, performed with clean dust or dry earth when water is unavailable or when using water would cause genuine harm. Allah says in the Quran: “If you do not find water, then do tayammum with clean earth” (Al-Maidah 5:6).
Tayammum is a concession (rukhsah) — a mercy of the Sharia that removes hardship when the normal means of purification is not possible.
When tayammum is permitted
Tayammum may substitute for wudhu or ghusl in these circumstances:
- No water available — you are travelling or in a place where water cannot be found within a reasonable distance
- Water is insufficient — there is only enough for drinking, and using it for wudhu/ghusl would cause thirst
- Medical restriction — using water would aggravate a wound, illness, or post-surgical condition
- Extreme cold — water is available but its use would cause genuine harm (illness, hypothermia) and no means of heating it exists
- Fear of time — the time of namaz will expire before water can be obtained (a limited dispensation; act quickly if water is found later)
What tayammum is performed on
Tayammum must be done with clean, dry earth — dust, sand, stone, clay, or any surface on which fine dust settles. It must be:
- Tāhir (pure) — free of visible impurity
- Dry — wet mud does not fulfil tayammum
- Natural — stone, brick, marble, or natural earth are valid; painted or varnished surfaces are not (since no earth-dust adheres)
If no earth is available, stone or fired brick may be used (the fine particles that adhere to the hands from striking suffice).
The faraidh of tayammum
Three acts are obligatory (fardh):
-
Niyyat — intention in the heart: “I perform tayammum in place of wudhu (or ghusl) to lift the state of hadath (minor/major impurity).”
-
Masah al-wajh — wiping the entire face with earth-dusted hands.
-
Masah al-yadayn — wiping both forearms from fingertips to (and including) the elbows.
How to perform tayammum
Step 1 — Niyyat: Form the intention in the heart.
Step 2 — First strike: Strike both palms flat on clean dry earth. Lightly shake off excess dust (a thin layer suffices; clumps are not needed).
Step 3 — Wipe the face: Using the inner surface of both palms together, wipe the entire face from forehead hairline to chin, and ear to ear. Every part of the face must be covered.
Step 4 — Second strike: Strike the palms on the earth a second time.
Step 5 — Wipe the right arm: Use the left hand (inner surface) to wipe the right hand and forearm from fingertips to elbow. Make sure to get between the fingers.
Step 6 — Wipe the left arm: Use the right hand to wipe the left hand and forearm in the same way.
That is the complete tayammum. It need not be done in flowing water; a single surface strike per wipe is sufficient.
How long tayammum lasts
Tayammum remains valid as long as:
- No hadath (impurity) occurs that would break wudhu (e.g., passing wind, using the toilet)
- Water does not become available
The moment water becomes accessible, tayammum is immediately invalidated and full wudhu or ghusl must be performed before the next act of worship.
Tayammum when substituting for ghusl
If tayammum substitutes for ghusl (due to janabat, haydh, etc.), the same two-strike process is performed with the same niyyat — specifying that it substitutes for ghusl. One tayammum covers all acts of worship until broken.
Can one tayammum cover multiple prayers?
Yes — a single valid tayammum covers as many prayers as needed until it is broken or water becomes available. You do not need to renew it before each salah.
Common mistakes
- Striking a smooth painted wall (no earth particles) — invalid; find natural stone or clean dust
- Omitting the face or part of an arm — invalid; the entire face and both forearms to the elbow are required
- Using tayammum when water is nearby and accessible — not permitted; seek the water first
- Forgetting niyyat — invalid; intention is a pillar (rukn) of tayammum
