On someone who is ill to perform

A: A sick person has to offer Salah according to their condition. They have thus to perform Salah standing, sitting in case of their inability to stand up, lying down on their sides in case of their inability to sit, or lying down on their back in case of their inability to lie down on their sides, while making gestures for Ruku‘ (bowing) and Sujud (prostration). The foregoing is based on a Hadith which is authentically reported from the Prophet (peace be upon him) on the authority of `Imran ibn Al-Husayn (may Allah be pleased with them both). Regarding Taharah, they have to make Wudu’ (ablution) if they are able to do so either by themselves or through the help of somebody else. Otherwise, they have to make Tayammum (dry ablution with clean earth). On the other hand, you do not have to make any Kaffarah for the fact that your father did not pray during the last month of his life. Hopefully he may be excused because he was ignorant of the foregoing ruling. Besides, Talqin is not Wajib (obligatory) and thus missing it is not a sin. And Allah knows best.
