One Who Is Certain That He Will not Find Water and Does not Look for Water
Issue No.619- If a person is sure that he cannot get water and does not, therefore, go in search of water and offers his prayer with tayammum, but realises after prayer that if he had made an effort he would have attained water, his prayer is void. Similarly, if after searching and not finding water, he made tayammum and offered his prayer then realized later that water was available at the place where he had searched, he should, as an obligatory precaution, make wuḍū and repeat the prayer and if the time of the prayer has elapsed, he should perform the qaḍā of the prayer.
