Question
What is the ruling for a traveler who forgot water in his car and prayed with tayammum, then remembered it before the time for the prayer had ended?
Answer
I say, and with God's success: He does not repeat the prayer; because he performed tayammum while not finding water, so his prayer is valid, just as if he performed tayammum while having a covered well that he is unaware of. This is different from if there is a garment in his luggage, because it is customary for clothes to be carried in luggage, and because the water in the luggage is intended for drinking, not for use. Refer to: Al-Wiqayah p. 112, and Al-Hidayah 1: 27, and God knows best.
