It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whatever inheritance was divided in the time of Jahiliyyah (pre-Islamic ignorance) will remain (as it is) according to the division of Jahiliyyah, and whatever inheritance Islam (its law) reaches will be according to the division of Islam."
No one narrated this hadith from Nafi' (may Allah have mercy on him) except Uqayl (may Allah have mercy on him), and no one from Uqayl (may Allah have mercy on him) except Ibn Lahi'ah (may Allah have mercy on him), and Muhammad bin Rumh (may Allah have mercy on him) is alone in narrating it.
