Hadith.5668 - Ibn Abi Umayr narrated from Jamil ibn Darraj, from Abu Al-Abbas, from Abu Abdullah (as), who said: "If a man divorces his wife while he is ill, she inherits from him as long as he remains in that illness, even if her waiting period (iddah) has ended - unless he recovers from his illness." I asked: "What if his illness lasts for a long time?" Imam (as) replied: "She inherits from him for up to one year."

Hadith.5669 - Hammad narrated from Al-Halabi, from Abu Abdullah (as), who was asked about a man who is on his deathbed and divorces his wife - whether his divorce is valid. Imam (as) said: "Yes, it is valid, and she will inherit from him. However, if she dies, he does not inherit from her."

Hadith.5670 - Salih ibn Said narrated from Yunus, from some of his companions, from Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq (as), who said: I asked Imam (as): "What is the reason that when a man divorces his wife while he is ill in a state of harm (idrar), she inherits from him, but he does not inherit from her?" He (as) replied: "It is due to the harm. The meaning of harm here is his intention to prevent her from inheriting from him, so he was held accountable by being obligated to allow her inheritance as a form of punishment."
