Yahya related to me from Malik that Thawr ibn Zayd ad-Dili said, "I heard that the Messenger of Allah ﷺ said, 'A house or land that has been divided in the Jahiliyya, it is according to the division of the Jahiliyya. A house or land which has not been divided before the coming of Islam is divided according to Islam.' "
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ أَيُّمَا دَارٍ أَوْ أَرْضٍ قُسِمَتْ فِي الْجَاهِلِيَّةِ فَهِيَ عَلَى قَسْمِ الْجَاهِلِيَّةِ وَأَيُّمَا دَارٍ أَوْ أَرْضٍ أَدْرَكَهَا الإِسْلاَمُ وَلَمْ تُقْسَمْ فَهِيَ عَلَى قَسْمِ الإِسْلاَمِ
