Is it permissible to offer more than one obligatory Salah (prayer) with one Tayammum (dry ablution with clean earth) if nothing occurred to invalidate it?
All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions.
A person who, for a valid excuse justifying performing Tayammum, performs Tayammum to offer one obligatory Salah is entitled to offer another obligatory Salah as long as the valid excuse is still in effect and his Tayammum is not invalidated by one of the annulments of Taharah (ritual purification) with water (i.e. Wudu’ and Ghusl). This is because Tayammum is a substitute for Taharah with water. Allah (Exalted be He) says (what means):
...but He wants to purify you
Moreover, the Prophet (peace be upon him) said:
“The whole earth has been made for me a Masjid (place of worship) and a Tahur (purifier).”
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
