The Shari`y obligations of the insane

A: If your father lost his mind, he would not be held accountable for not performing Salah or observing Sawm in this state. That is because Taklif (meeting the conditions to be held legally accountable for actions) is connected to reason, so nothing is due on you in this regard.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
