What is the ruling on delaying the prayer from its time due to the lack of water?

The questioner : In a settled area, if water is unavailable and it is known that water will be brought for the second prayer, for example, our Shaykh, suppose we need to pray Dhuhr and 'Asr is the second prayer, meaning the water will arrive, which is better, my teacher? Should I perform tayammum so I can pray Dhuhr in its time, or should I delay it, my teacher, on the basis that it is permissible for us to combine the prayers by delaying them now?

The Shaykh : No, no, there is no need to delay it. He should pray the prayer in its time using tayammum.

The questioner : May Allah reward you with good.

The Shaykh : And beware of that.

The questioner: Peace be upon you.

The Shaykh : And upon you be peace, and the mercy of Allah and His blessings.
