An old man who can neither observe Sawm nor perform Wudu'

Q: My father is very old and is unable to stand without my help. He was not able to observe Sawm (Fast) in the current Ramadan. He usually performs Tayammum (dry ablution with clean earth) to offer Salah (Prayer), as he is not able to perform Wudu' (ablution). He offers Salah either while sitting or (Part No. 9; Page No. 80) lying on his side. What is the ruling on this?

A: First: If your father is unable to observe Sawm due to his old age, he should feed one Miskin (needy person) an amount of about one half a Sa` (1 Sa` = 3 kg. Approx.) of dates, wheat, or similar staple food of the country for each day on which he breaks Sawm. Second: If your father is unable to use water or cannot find someone to help him use it, he is permitted to perform Tayammum and offer Salah according to his ability, i.e., if he is unable to offer it while standing, he can offer it while sitting.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
