A man who cannot find sufficient water: Does he perform tayammum while in prison?

The questioner : Some prisoners are placed in special cells due to their specific cases. These cells are approximately one and a half meters by one and a half meters, and they are not allowed to leave them at all. They remain sitting inside because they are problematic or dangerous from a political standpoint or otherwise, so they do not want them to mix with the other prisoners. They eat, drink, and urinate in there. May Allah reward you.

The Shaykh : Allahu Akbar.

The questioner : Sometimes very little water is brought to them, so they are unable to perform wudu. Should they perform tayammum using the wall, for example, as some people do, or not?

The Shaykh : It is necessary. It is necessary.

The questioner : If the wall is made of iron...

The Shaykh : He must do so, as long as he is unable to perform wudu.

The questioner : O Shaykh, to complete the brother's question regarding the boy who places money in the house. A man—image—I want you to clarify to me whether it includes what was said.
