What is the ruling on one who committed a heinous act with his mother while intoxicated and then burned her?

Question:
I have a brother who is always intoxicated. One night, while drunk, he committed a heinous act with his mother, may Allah protect us, and then burned her. Therefore, I seek your guidance on what to do regarding this matter.

Answer:
This is a serious act, may Allah grant us safety, and a great evil, we seek refuge in Allah. It is obligatory to report his case to the authorities, may Allah grant us safety. There is no power or strength except if he has repented, shown remorse, and desisted. Otherwise, it is obligatory to report him to the authorities so that he is imprisoned like his peers, disciplined, and the prescribed punishment is carried out against him, may Allah grant us safety. This is if you have two just witnesses against him or if he confesses. But if he has repented, shown remorse, and left the falsehood he was upon, then do not deal with him after that. However, if he is still in his affliction and evil, you should report his case to the state, may Allah grant us safety.
