Question
What is the ruling on someone who performed tayammum and then found water, washed each limb twice or thrice, but missed one of his legs, for example?
Answer
I say, with Allah's guidance: His tayammum is invalidated according to the chosen opinion; because if he had sufficed with washing once, it would have been enough. See: Al-Hadiyah Al-Alaiyah, p. 38, and Sharh Al-Ziyadat, Q3/A, and Allah knows best.
