Question:
Honorable Shaykh, may Allah grant you success. A questioner says: A person did not have water, so he performed tayammum and prayed. Then, after that, water became available within the time. Is it obligatory for him to repeat the prayer?
Answer:
If water becomes available while he is praying, he must break off the prayer and perform wudu. As for if water does not become available until after he has prayed, his prayer is valid, but he must perform wudu for future prayers. There is a riddle in this: "The donkey brayed, and the prayer became invalid." When is this? Does the braying of a donkey invalidate the prayer? The braying of the donkey that is carrying water, yes.
