Tayammum

Dry ablution — purification with clean earth in place of water — a concession (rukhṣa) of the sharī’a. Its scope was widened by a Companion’s ijtihad at Dhat al-Salasil.

Definition

When water is unavailable or its use would cause harm, one may purify with clean earth for prayer. It substitutes for both wudu and — by unanimous consensus — ghusl.

How it appears in the Seerah

On a freezing desert night during Dhat al-Salasil (8 AH), Amr ibn al-As had a wet dream and, fearing a cold ghusl would kill him, did tayammum and led Fajr. Reported to the Prophet ﷺ, Amr cited “do not kill yourselves; indeed Allah is Merciful to you” (Q 4:29). The Prophet ﷺ laughed and did not rebuke him — the first recorded case of a Companion choosing tayammum with water present for a legitimate reason.

Evidences

• Quran 5:6 (the ayah of purification and its concession) and Q 4:29 (Amr’s reasoning against self-harm).
• Amr’s incident, in the hadith collections (Abu Dawud and others).

Lessons

• Tayammum replaces ghusl, not merely wudu (consensus).
• It is permitted even when water is available for a valid excuse — e.g. extreme cold, or a skin ailment water must not touch.
• One who prays after tayammum is not diminished in his fitness to lead the prayer.
• A window into the sahaba’s ijtihad in the Prophet’s ﷺ lifetime, and into balancing fidelity to the text with the sharī’a’s regard for real circumstances — the perennial tension between literalism and reasoned application.
