It was narrated that Ibn 'Umar said: "I used to sell camels, and I used to buy gold for silver and silver for gold, Dinar for Dirham and Dirham for Dinar. I asked the Prophet (ﷺ) about that, and he said: 'If you take one of them and give the other, then you and your companion should not separate until everything is clear (i.e., the exchange is completed).’” (Hasan) Another chain with similar wording.

حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ بْنِ حَبِيبٍ، وَسُفْيَانُ بْنُ وَكِيعٍ، وَمُحَمَّدُ بْنُ عُبَيْدِ بْنِ ثَعْلَبَةَ الْحِمَّانِيُّ، قَالُوا حَدَّثَنَا عُمَرُ بْنُ عُبَيْدٍ الطَّنَافِسِيُّ، حَدَّثَنَا عَطَاءُ بْنُ السَّائِبِ، أَوْ سِمَاكٌ - وَلاَ أَعْلَمُهُ إِلاَّ سِمَاكًا - عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنِ ابْنِ عُمَرَ قَالَ كُنْتُ أَبِيعُ الإِبِلَ فَكُنْتُ آخُذُ الذَّهَبَ مِنَ الْفِضَّةِ وَالْفِضَّةَ مِنَ الذَّهَبِ وَالدَّنَانِيرَ مِنَ الدَّرَاهِمِ وَالدَّرَاهِمَ مِنَ الدَّنَانِيرِ ‏.‏ فَسَأَلْتُ النَّبِيَّ ـ صلى الله عليه وسلم ـ فَقَالَ ‏ "‏ إِذَا أَخَذْتَ أَحَدَهُمَا وَأَعْطَيْتَ الآخَرَ فَلاَ تُفَارِقْ صَاحِبَكَ وَبَيْنَكَ وَبَيْنَهُ لَبْسٌ ‏"‏ ‏.‏
