Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ آدَمَ حَدَّثَنَا إِسْرَائِيلُ عَنْ سِمَاكٍ عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنِ ابْنِ عُمَرَ قَالَ كُنْتُ أَبِيعُ الْإِبِلَ بِالْبَقِيعِ فَأَبِيعُ بِالدَّنَانِيرِ وَآخُذُ الدَّرَاهِمَ وَأَبِيعُ بِالدَّرَاهِمِ وَآخُذُ الدَّنَانِيرَ فَأَتَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ يُرِيدُ أَنْ يَدْخُلَ حُجْرَتَهُ فَأَخَذْتُ بِثَوْبِهِ فَسَأَلْتُهُ فَقَالَ إِذَا أَخَذْتَ وَاحِدًا مِنْهُمَا بِالْآخَرِ فَلَا يُفَارِقْكَ وَبَيْنَكَ وَبَيْنَهُ بَيْعٌ.
English Translation
Yahya ibn Adam narrated to us: Isra'il narrated from Simak from Sa'id ibn Jubayr from Ibn Umar who said: I used to sell camels at al-Baqi. I would sell for dinars and take dirhams, and sell for dirhams and take dinars. I came to the Prophet (peace be upon him) while he was about to enter his chamber. I took hold of his garment and asked him. He said: If you take one of them in exchange for the other, do not part from him while there is still a transaction between you.
