Machine translationRead the Arabic original
Question:
He says: Honorable Shaykh, my grandfather is eighty-four years old, and his mind comes and goes with regard to prayer and fasting. What is the ruling in this case, given that he is unable to perform wudu'?
Answer:
As for wudu', if he is unable to perform it, he should perform tayammum with clean earth. As for if his mind has gone and he has no mind left for a long period, then he owes nothing. But if his mind is with him, though it is weak, and he may sometimes be forgetful or inattentive, then he fasts and prays. Yes.
