What is the term for the dry ablution performed using clean earth or sand, permitted when water is unavailable or harmful to use?

Explanation

– Tayammum refers to the dry ablution performed using clean earth, sand, or a similar surface, permitted specifically when water is unavailable, insufficient, or would be harmful to use due to illness.
– This practice reflects Islamic law’s broader emphasis on practical ease, ensuring believers can maintain their prayer obligations even when standard water-based purification is not feasible.
– For exams, remember that this concession is explicitly mentioned in the Quran, Surah An-Nisa, verse 43, providing clear guidance on this alternative method of purification.
