The ruling on the prayer of one who is unable to stand, in his home

Question:
He says: Honorable Shaykh, may Allah grant you success. I am an old man, and I cannot pray while standing. So, should I pray while sitting? At times I fall to the ground while on my way to the mosque. Do I have a dispensation to pray at home if I am unable to walk? And should I pray while sitting or standing?

Answer:
As for one who is unable to stand, he prays while sitting. The Prophet (peace and blessings be upon him) said: "The sick person prays standing, and if he cannot, then sitting, and if he cannot, then on his side." If he is unable to stand, he prays while sitting, and praise be to Allah. The Prophet (peace and blessings be upon him) prayed the obligatory prayer while sitting when something happened to his foot, and during his final illness, the Prophet (peace and blessings be upon him) prayed sitting for his Companions. So the sick person prays while sitting. Likewise, the very old man who is unable to stand, may Allah reward you, praise be to Allah. As for falling while on his way to the mosque, this is also an excuse, because he may fall and be injured as a result of the fall. So this is an excuse for him to pray in his home, unless he finds a vehicle to ride in that takes him to the mosque, such as a car. If he rides the car, the excuse is removed by this.
