A patient is credited with the deeds that he used to do when healthy

Ata bin Abu Rabah said that Ibn Abbas asked him if he would like him to show him a woman who would go to paradise. So, he said that he would certainly like (him to show him the woman). Ibn Abbas said to him. "This is a black woman who came to the Prophet and said to him, "Messenger of Allah, I am subject to fits and become uncovered, so make a supplication to Allah to cure me, "The Prophet (ﷺ) said to her, "If you endure it patiently, you will be rewarded with paradise, but if you wish I will make a supplication to Allah to cure you." The woman said, ’I shall endure it. But, (when I get fits) I become uncovered, make supplication to Allah that I may not become uncovered. So, he made a supplication for her."
