Yazid (may Allah have mercy on him) says that Tamim al-Dari (may Allah be pleased with him) said: "O Messenger of Allah (peace and blessings be upon him)! If a disbeliever accepts Islam at the hands of a Muslim, what is the practice?" He (peace and blessings be upon him) said: "He has more right than other people over his life and his death."
The Shaykh (may Allah have mercy on him) said: So, with Qabisah mentioned in it, the hadith reverts to being mursal.
