´It was narrated that ‘Abdullah bin Mawhab said:` “I heard Tamim Ad- Dari say: ‘I said: O Messenger of Allah, what is the Sunnah concerning a man from among the People of the Book who becomes a Muslim at the hands of another man?’ He said: ‘He is the closest of all people to him in life and in death.’”

Benefits and Issues:
➊ This is also a form of wala’ (loyalty) that a non-Muslim accepts Islam at the hands of a Muslim. The other relatives of this new Muslim, being non-Muslim, cannot be his heirs; therefore, the one who brought him to Islam will be his heir.
➋ If the new Muslim has other Muslim heirs, then they will inherit his estate. However, if those heirs are entitled to fixed shares (ashab al-furud) and he has no Muslim agnatic (asaba) relatives, then the one who brought him to Islam will become his agnatic heir and inherit from him. And Allah knows best.
