The ruling on one who performed tayammum and prayed, then found water

Question:
Our brother asks and says: How do I pray if I cannot find water for wudu'? And if I have prayed after performing tayammum and then find water, do I repeat the prayer?

Answer:
If the water is near you and you hope to obtain it, then it is obligatory for you to search for water in the places where you hope to find it, and in any locations around you that you can reach. You must seek water in the vicinity and nearby, as the scholars say.
As for if it is most likely in your opinion that you cannot reach the water, and there is no water around you that you can reach, then you perform tayammum and pray, and your prayer is valid. This is based on the saying of Allah the Exalted: As for if you performed tayammum and prayed, and then you found water near you, if this was the result of your negligence and not seeking or searching, then you repeat the prayer; you perform wudu' and repeat the prayer. But if you exerted effort, searched, and sought water and did not find it, then you performed tayammum and prayed, your prayer is valid. Yes.
