The ruling on the prayer of an elderly person who does not know what he is saying

Question:
The questioner says: What is the ruling on one who is unable to pray due to his advanced age, and he says, “I do not know what to say in my prayer”? Is he excused? Or is it that he was not missing the prayer? He says: One who is unable to pray due to his advanced age, and he says, “I do not know what to say in my prayer.” Is it permissible for him, knowing that he was not missing the prayer?

Answer:
As long as his mind is present, the condition does not drop the prayer from him, but he prays according to his condition. Allah the Exalted said: The Prophet (peace and blessings be upon him) said: The Prophet prays while fasting, so if he is not able, then sitting; if he is not able, then on his side. And if he does not know anything of the Qur'an, he glorifies Allah, declares His greatness, and affirms His oneness, then he recites as the Prophet (peace be upon him) said. So recite. Otherwise, praise Allah and declare His greatness and affirm His oneness. Then do not leave the prayer. And his mind is present.
