What is the ruling on a traveler who performs tayammum (dry ablution with clean earth) while water is available and villages are nearby?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: If I am traveling and I have sufficient water and the villages are close, is it permissible for me to perform tayammum? And what is the ruling on one who does so on the basis that he does not know what will happen to him in the future?

Answer:
If the water is not sufficient for his need and for ritual purity, he drinks the water for his need and performs tayammum with earth. However, if the water is sufficient with him, enough for his need and enough for ritual purity, it is not permissible for him to perform tayammum. Or if he has water nearby that he can go to, it is not permissible for him to travel without it. Allah the Exalted says: “So if you do not find water, then perform tayammum.” If he finds water, whether it is sufficient with him or it is near him, it is not permissible for him to travel without it.
