代 净
代净：在没有水的地方或有病不能用水的时候，可用土凈代替小净。
安拉说：「如果你们有病或旅行，你们可趋向洁净的地面，用土抹你们的脸和你们的手。」【4：43】
土凈的次序：立意后，用两手在洁净的沙、或土、或石上按拍，然后涂抹脸部，再一拍涂抹两手至手肘先右后左。完毕时念「作证言」 (Kalimatun-Shahaadah)
如小净一样。
4. Tayammum
Tayammum –
Dry Ablution: In the absence of water or because of the
need to avoid water due to the medical reasons, Tayammum
(Dry Ablution) is performed.
Allah said, ‘If
you are ill, or on a journey, and you find no water,
perform Tayammum with clean earth and rub therewith your
faces and hands.’【4：43】
The Tayammum procedure：After
making Intention, strike both palms on clean sand (or
anything containing sand or dust, like a wall) or a
stone. Pass the palms over the face once. Strike the
sand or a stone again with the palms. Rub the hands up
to the elbow, right first then left. Finish with the
word of Testimony (Kalimatun-Shahaadah) as for Minor
Ablution (Wudhu).
