What is the ruling regarding my relative's cessation of prayer due to her inability to control the emission of gas?

Interrupting prayer due to urinary incontinence or inability to control flatulence is a grave error, for prayer is one of the greatest pillars of the religion and the dividing line between disbelief and faith. It is not permissible to abandon it under any circumstances. Even if the worshipper is unable to stand, he should pray sitting or on his side. Perhaps your relative's abandonment of prayer was due to her ignorance of the ruling. We ask Allah to excuse her and forgive her.
