Is Tayammum permissible if one fears missing the Eid prayer?
Chapter on Tayammum
Al-Mughni
Book of Purification
Primary text
Tayammum is not permissible if one fears missing the Eid prayer. The evidence is the general rule stating that one capable of finding water must use it, as established by the Quranic verse and the Hadith mentioned previously, alongside the general principle prohibiting the abandonment of purification requirements due to fear of missing a specific act.

Al-Awza'i and the companions of Al-Ra'y permit Tayammum because missing the entire Eid prayer is feared, equating the situation to being without water.
