وَيَجُوزُ أَنْ يَؤُمَّ الْمُتَيَمِّمُ الْمُتَوَضِّئِينَ،
Meaning: A person performing valid tayammum may lead people who have performed wudu.
Tayammum is legally authorized purification when water is unavailable or its use is excused. If its conditions are fulfilled, the imam’s prayer and the followers’ prayers are valid. This does not take the same ruling as leadership under chronic incontinence.
