[Machine] And the companions of the Messenger of Allah ﷺ used to gather during his lifetime and good health. Allah called upon them: whoever hears the Messenger of Allah ﷺ mentioning a matter related to his grandfather, stand up.' Ma'qil ibn Yasar stood up and said: I heard the Messenger of Allah ﷺ say: "A duty will be brought forth in which there is a grandfather, and he will be given a third or a sixth." He asked: "What is the duty?" He replied: "I do not know." He asked: "What prevented you from knowing?"  

أحمد:٢٠٣٠٩ – حَدَّثَنَا عَمْرُو بْنُ الْهَيْثَمِ أَبُو قَطَنٍ حَدَّثَنَا يُونُسُ يَعْنِي ابْنَ أَبِي إِسْحَاقَ عَنْ أَبِيهِ عَنْ عَمْرِو بْنِ مَيْمُونٍ شَهِدَ عُمَرَ قَالَ

وَقَدْ كَانَ جَمَعَ أَصْحَابَ رَسُولِ اللهِ ﷺ فِي حَيَاتِهِ وَصِحَّتِهِ فَنَاشَدَهُمُ اللهَ مَنْ سَمِعَ رَسُولَ اللهِ ﷺ ذَكَرَ فِي الْجَدِّ شَيْئًا فَقَامَ مَعْقِلُ بْنُ يَسَارٍ فَقَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ أُتِيَ بِفَرِيضَةٍ فِيهَا جَدٌّ فَأَعْطَاهُ ثُلُثًا أَوْ سُدُسًا قَالَ وَمَا الْفَرِيضَةُ؟ قَالَ لَا أَدْرِي قَالَ مَا مَنَعَكَ أَنْ تَدْرِيَ؟

[Machine] That Umar gathered the companions of the Messenger of Allah, ﷺ , to discuss a matter pertaining to inheritance. He asked them if anyone had heard the Messenger of Allah, ﷺ , mention anything about inheritance. Maqil ibn Yasar Al-Muzani stood up and said, "I heard the Messenger of Allah, ﷺ , mention a duty that includes inheritance and he gave two-thirds or one-half of it." Umar asked him, "What is the duty?" He replied, "I do not know." Umar kicked him with his foot and said, "You don't know!"  

الكبرى للنسائي:٦٢٩٩ – أَخْبَرَنَا سُلَيْمَانُ بْنُ سَلْمٍ الْبَلْخِيُّ قَالَ أَخْبَرَنَا النَّضْرُ يَعْنِي ابْنَ شُمَيْلٍ قَالَ أَخْبَرَنَا يُونُسُ يَعْنِي ابْنَ أَبِي إِسْحَاقَ عَنْ أَبِي إِسْحَاقَ عَنْ عَمْرِو بْنِ مَيْمُونٍ
