An insane person is exempted from Hajj and other acts of worship
Q: My 65-year-old maternal uncle died and he (Part No. 10; Page No. 37) (may Allah be merciful to him) was an insane person, who lacked good disposition of his affairs. My mother told me that he was afflicted with this condition since he was 15 years old. I understood from you previously that an insane person is exempted from the legal duties.
Is he exempted from Hajj?
Please give us your Fatwa (legal opinion issued by a qualified Muslim scholar). May Allah reward you with the best. I hope I will receive your Fatwa soon, before the time of Hajj for this year, in order to perform Hajj on his behalf, if Hajj is obligatory on him. May Allah reward you with the best.
An insane person is exempted from Hajj and from other religious acts of worship, because the Prophet (peace be upon him) says:
There are three (persons) whose actions are not recorded,
i.e. they are not called to account for their deeds. He mentioned among them "an insane person until he recovers." As the ruling is as mentioned, do not perform Hajj on his behalf. The insane person in question is defined as the one who lacks reason so that he is like a mad person.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
