حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ ، حَدَّثَنَا شُعْبَةُ ، قَالَ: سَمِعْتُ جَبَلَةَ بْنَ سُحَيْمٍ ، قَالَ : كَانَ ابْنُ الزُّبَيْرِ يَرْزُقُنَا التَّمْرَ ، قَالَ: وَقَدْ كَانَ أَصَابَ النَّاسَ يَوْمَئِذٍ جَهْدٌ ، وَكُنَّا نَأْكُلُ فَيَمُرُّ عَلَيْنَا ابْنُ عُمَرَ وَنَحْنُ نَأْكُلُ ، فَيَقُولُ: لاَ تُقَارِنُوا فَإِنَّ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى عَنِ الإِقْرَانِ ، إِلاَّ أَنْ يَسْتَأْذِنَ الرَّجُلُ أَخَاهُ. قَالَ شُعْبَةُ: لاَ أُرَى هَذِهِ الْكَلِمَةَ إِلاَّ مِنْ كَلِمَةِ ابْنِ عُمَرَ يَعْنِي الاِسْتِئْذَانَ -.

Jabalah bin Suhaim said: "Ibn Az-Zubair used to provide us with dates, as the people had been stricken with famine at that time. We were eating and Ibn 'Umar passed by us while we were eating, and he said: 'Do not eat two together, for the Messenger of Allah (s.a.w) forbade eating two together, unless a man asks his brother for permission."' Shu'bah (a narrator) said: "I think that these are the words of Ibn 'Umar," i.e. about asking permission.
