The ruling on fasting on behalf of a father who has died

Question:
If a father dies and he has three Ramadans of fasting left, should I fast on his behalf, or what should I do?

Answer:
If the father died while being negligent, having been spared by Allah and healed by Allah from illness, but he was lax; then it is prescribed for you to fast on his behalf, you and your brothers; because the Prophet (peace and blessings be upon him) said: And a group asked him, each one asking, saying: O Messenger of Allah, my father died and he had such-and-such, should I fast on his behalf? And another said: My mother died and she had such-and-such, should I fast on her behalf? And another said: My sister died and she had such-and-such, should I fast on her behalf? So the Prophet (peace and blessings be upon him) said: .
So it is upon you to make up that fast, you and your brothers; it is prescribed for you, meaning: it is a recommended practice (sunnah) for you. If you do not make it up for him; then you feed on his behalf from his wealth, feeding one poor person for each day. This is if you do not make up the fasting for him. And the recommended practice (sunnah) is fasting on behalf of your father if he was healed from his illness and was lax. But if he died in his illness—he was not healed—and the illness continued with him until he died, then there is no making up and no feeding. There is no making up upon him, and no feeding.

The student: Is it dropped from him?

Question: What about the prayer?
