حَدَّثَنَا الْعَبَّاسُ بْنُ جَعْفَرٍ، حَدَّثَنَا مُوسَى بْنُ دَاوُدَ، حَدَّثَنَا مُحَمَّدُ بْنُ مُسْلِمٍ الطَّائِفِيُّ، عَنْ عَمْرِو بْنِ دِينَارٍ، عَنْ أَبِي الشَّعْثَاءِ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ كُلُّ قَسْمٍ قُسِمَ فِي الْجَاهِلِيَّةِ فَهُوَ عَلَى مَا قُسِمَ وَكُلُّ قَسْمٍ أَدْرَكَهُ الإِسْلاَمُ فَهُوَ عَلَى قَسْمِ الإِسْلاَمِ ‏"‏ ‏.‏

It was narrated from Ibn `Abbas that the Messenger of Allah (ﷺ) said:“Every division that was allocated according to (the rules of) the Ignorance days, stands as it is, and every division that was allocated according to (the rules of) Islam, stands according to the rules of Islam.”
