Question: Many of those who are sick pray on their beds, as they are unable to move; so [as a result] they pray without wudhoo. And there are amongst them those who pray in other than the direction of the qiblah, [so] what is the ruling regarding the prayer of these sick people?
Response: It is befitting for us to know [and understand] the general principle in the Sharee’ah – as indicated by the Book of Allaah and the Sunnah of His Messenger ﷺ – that every Muslim must fear Allaah as much as he is able. So every obligation is obligatory upon him in accordance with his ability; if he is incapable, [then this obligation] is dropped.
Allaah Subhaanahu wa Ta’aala says:
And He Subhaanahu wa Ta’aala says:
And He Subhaanahu wa Ta’aala says:
And in the authentic hadeeth, the Prophet ﷺ said:
So these sick people mentioned [in this question] – those who pray on their beds, in impure (unclean) clothing, and in other than the direction of the qiblah – then [regarding] all of them [I say] if they have done what they are able to from that which is required of them in their salaah, and are unable to fulfill the other requirements, then they are excused and as such not required to do so, and will not be sinful for leaving them.
