حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ عَبْدِ الْكَرِيمِ، حَدَّثَنَا سُنَيْدُ بْنُ دَاوُدَ، عَنْ خَالِدِ بْنِ حَيَّانَ الرَّقِّيِّ، أَنْبَأَنَا عَلِيُّ بْنُ عُرْوَةَ الْبَارِقِيُّ، حَدَّثَنَا يُونُسُ بْنُ يَزِيدَ، عَنْ أَبِي الزِّنَادِ، عَنْ خَارِجَةَ بْنِ زَيْدٍ، قَالَ رَأَيْتُ رَجُلاً سَأَلَ أَبِي عَنِ الرَّجُلِ، يَغْزُو فَيَشْتَرِي وَيَبِيعُ وَيَتَّجِرُ فِي غَزْوِهِ فَقَالَ لَهُ أَبِي كُنَّا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم بِتَبُوكَ نَشْتَرِي وَنَبِيعُ وَهُوَ يَرَانَا وَلاَ يَنْهَانَا ‏.‏
