[Machine] The Messenger of Allah ﷺ ruled that a man should donate to another man and his descendants, except if it happens to be your descendant, then it is for me and my descendants. Indeed, it is for whoever is given it and his descendants. Al-Uqail also narrated it in the sense of narrating from these people, while Al-Awza'i disagreed with them and narrated it from Al-Zuhri.
أَنَّ رَسُولَ اللهِ ﷺ قَضَى بِالْعُمْرَى أَنْ يَهَبَ الرَّجُلُ لِلرَّجُلِ وَلِعَقِبِهِ وَاسْتَثْنَى إِنْ حَدَثَ بِعَقِبِكَ فَهُوَ إِلِيَّ وَإِلَى عَقِبِي إِنَّهَا لِمَنْ أُعْطِيَهَا وَلِعَقِبِهِ وَرَوَاهُ أَيْضًا عُقَيْلٌ بِمَعْنَى رِوَايَةِ هَؤُلَاءِ وَخَالَفَهُمُ الْأَوْزَاعِيُّ فَرَوَاهُ عَنِ الزُّهْرِيِّ
