[Machine] The lifetime that the Messenger of Allah ﷺ allowed himself to say is for you and your descendants. As for when he said it is for you as long as you live, it returns to its owner. This was informed to us by Abu Abdullah Al-Hafiz, who narrated to us Abu Al-Fadl Ibn Ibrahim, who narrated to us Ahmad Ibn Salamah, who narrated to us Ishaq Ibn Ibrahim, who narrated to us Abdul Razzaq, who mentioned it in a similar way. Ma'mar said that Al-Zuhri used to issue rulings on it.
إِنَّمَا الْعُمْرَى الَّتِي أَجَازَ رَسُولُ اللهِ ﷺ أَنْ يَقُولَ هِيَ لَكَ وَلِعَقِبِكَ فَأَمَّا إِذَا قَالَ هِيَ لَكَ مَا عِشْتَ فَإِنَّهَا تَرْجِعُ إِلَى صَاحِبِهَا 11965 وَأَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ أنبأ أَبُو الْفَضْلِ بْنُ إِبْرَاهِيمَ ثنا أَحْمَدُ بْنُ سَلَمَةَ ثنا إِسْحَاقُ بْنُ إِبْرَاهِيمَ ثنا عَبْدُ الرَّزَّاقِ فَذَكَرَهُ بِمِثْلِهِ زَادَ قَالَ مَعْمَرٌ وَكَانَ الزُّهْرِيُّ يُفْتِي بِهِ
