عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ
أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَا كَانَ مِنْ مِيرَاثٍ قُسِّمَ فِي الْجَاهِلِيَّةِ فَهُوَ عَلَى قِسْمَةِ الْجَاهِلِيَّةِ وَمَا كَانَ مِنْ مِيرَاثٍ أَدْرَكَهُ الْإِسْلَامُ فَهُوَ عَلَى قِسْمَةِ الْإِسْلَامِ»
Abdallah ibn Umar reported God’s Messenger as saying, “An estate which was divided in the pre-Islamic period following the division in force then, but any estate in Islamic times must follow the division appointed by Islam.”
