Do Ahlulbait (PBUT) know the exact time and details of their death, or do they only have a general idea?

Answer

In the name of Allah, my dear, every believer has two appointed times, one of which is predetermined and cannot be changed, and the other is not predetermined and can be influenced by various factors and conditions. The Imam (PBUH) undoubtedly has knowledge of the details of both predetermined and non-predetermined appointed times. The Imam (PBUH) acts in accordance with the command of Allah Almighty. Allah knows best.
