A person who Lose his senses During salaah

Q: Salaah-707: What do the Ulema of Deen and the Muftis have to say about a person who suffers from a mental disease because of which he sometimes loses his senses and has no control over his mind and movements for a few minutes? For example, he may look around in salaah, stand up when he should be sitting or stretches out his feet while sitting. Such attacks may occur every ten to fifteen days, making it more or less twice a month. Can salaah be performed behind such a person as an Imaam? What is the ruling when such an attack occurs in salaah? Will the salaah of all the Muqtadis have to be repeated or can someone from the first row take over and complete the salaah? After an attack of about two to three minutes, he then regains his composure.

Answer: The salaah performed behind such an Imaam when he is in control of his sense is valid but the salaah performed behind him when he loses Control is invalid. A Muqtadi may not complete the salaah and it will have to be repeated. i It is therefore best tor such a person not to lead the salaah until he is well. And Allaah knows best what is most correct.
