Prisoners in Solitary Confinement Performing Dry-Ablution [Tayammum]
by The Albaani Blog
Questioner: Some prisoners, O Shaikh of ours, are put in special cells, ya’nee, due to their particular circumstances, and these cells are about a metre and a half by a metre and a half. They’re not allowed to leave them at all, ya’nee, they stay in them because they are under suspicion or are dangerous from a political standpoint or other such things, so they eat, drink and urinate—may Allaah honour you—in them, sometimes they are given water [but] only a very little so they can’t perform ablution [wudoo]. So should they perform dry-ablution [tayammum] using the wall, for example, as some people do?
Al-Albaani: Definitely, he must do that since he can’t perform wudoo.
