حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَعَبْدُ بْنُ حُمَيْدٍ، - وَاللَّفْظُ لِعَبْدٍ - قَالاَ أَخْبَرَنَا عَبْدُ، الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ جَابِرٍ، قَالَ إِنَّمَا الْعُمْرَى الَّتِي أَجَازَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ يَقُولَ هِيَ لَكَ وَلِعَقِبِكَ ‏.‏ فَأَمَّا إِذَا قَالَ هِيَ لَكَ مَا عِشْتَ ‏.‏ فَإِنَّهَا تَرْجِعُ إِلَى صَاحِبِهَا ‏.‏ قَالَ مَعْمَرٌ وَكَانَ الزُّهْرِيُّ يُفْتِي بِهِ ‏.‏
