Hadith.5468 - As for the narration of Ali ibn Asbaṭ from Thaʿlabah from Abu Al-Hasan Amr ibn Shaddad Al-Azdi from Ammar ibn Musa from Abu Abdullah (as), who said: "A man has the most right over his wealth as long as his soul remains in him. If he bequeaths all of it, it is permissible for him."

Hadith.5469 - And a confirmation of this is what was narrated by Ismaʿil ibn Abi Ziyad Al-Sakuni from Imam Jafar ibn Muhammad Al-Sadiq (as) from his father, Abu Abdullah Imam Muhammad ibn Ali Al-Baqir (as), that he was asked about a man who dies without leaving behind an heir or any male relative (Aṣabah). Imam (as) said: "He may bequeath his wealth as he wishes among the Muslims, the poor, and the wayfarer."

Hadith.5470 - Al-Hasan ibn Mahbub narrated from Abu Walad, who said: I heard Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq (as) say: "Whoever intentionally kills himself will be in the Fire of Hell, abiding therein forever." Imam (as) was asked: "What if he had made a will (waṣiyyah) and then deliberately killed himself immediately after? Will his will be carried out?" Imam (as) replied: "If he made the will before committing any harmful act against himself, whether by injury or any other action, then his will is valid regarding one-third of his wealth. However, if he made the will after having already harmed himself - by injuring himself or committing an act intending death - then his will is not valid."
