My father passed away, and he used to pray only at home due to hardship. What should I do for him after his death?

Question:
May Allah reward you, Your Eminence, father. The questioner says: My father was about sixty years old, and before his passing, he did not say "May Allah reward you." My father was about sixty years old, and before his passing, he did not pray the Friday prayer or the congregational prayer in the mosque; because he lives in a building on the sixth floor, and it is difficult for him to go down for every obligatory prayer. So what should I do for him after his death, since this matter troubles me greatly?

Answer:
If it is as you mentioned, that he had hardship in going down for the Friday prayer and the congregational prayer, but the Friday prayer does not repeat; what is difficult for him is going down for the Friday prayer, so he erred in abandoning the Friday prayer. As for the congregational prayer, if he was unable to do so and it was difficult for him, then he is excused. In any case, he is a Muslim. Seek forgiveness for him, make du'a for him, and give charity on his behalf. He is a Muslim, but he committed one of the sins. Perhaps Allah will say to you: perhaps he was striving in himself, thinking he was on the right path, when he was not on the right path. Yes. But as long as he is a Muslim, seek forgiveness for him, make du'a for him, and give charity on his behalf. Yes.
