[Machine] I used to sell camels in Al-Baqi' and I would receive silver coins and give out dirhams. Then I would sell with the dirhams and receive silver coins again. So I went to the Prophet ﷺ while he was going to enter his room. I caught hold of his garment and asked him, so he said, "If you take one of them by the other, it will not separate from you and there will be a transaction between you and him."  

كُنْتُ أَبِيعُ الْإِبِلَ بِالْبَقِيعِ فَأَبِيعُ بِالدَّنَانِيرِ وَآخُذُ الدَّرَاهِمَ وَأَبِيعُ بِالدَّرَاهِمِ وَآخُذُ الدَّنَانِيرَ فَأَتَيْتُ النَّبِيَّ ﷺ وَهُوَيُرِيدُ أَنْ يَدْخُلَ حُجْرَتَهُ فَأَخَذْتُ بِثَوْبِهِ فَسَأَلْتُهُ؟ فَقَالَ إِذَا أَخَذْتَ وَاحِدًا مِنْهُمَا بِالْآخَرِ فَلَا يُفَارِقْكَ وَبَيْنَكَ وَبَيْنَهُ بَيْعٌ  

[Machine] "I used to sell camels in the (market) of Al-Baqi' and would take (payment) in dinars and give (change) in dirhams. I would also sell in dirhams and take (payment) in dinars. So I came to the Prophet ﷺ while he was in Hafsa's house and said, 'O Messenger of Allah, I sell camels in Al-Baqi' and take (payment) in dinars and give (change) in dirhams. The Prophet ﷺ said, 'There is no harm if you take them at their current day price and separate them, as long as there is no transaction between you two (i.e., no interest-based transaction).'"  

كُنْتُ أَبِيعُ الْإِبِلَ فِي الْبَقِيعِ فَأَبِيعُ بِالدَّنَانِيرِ وَآخُذُ الدَّرَاهِمَ وَأَبِيعُ بِالدَّرَاهِمِ وَآخُذُ الدَّنَانِيرَ فَأَتَيْتُ النَّبِيَّ ﷺ وَهُوَ فِي بَيْتِ حَفْصَةَ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنِّي أَبِيعُ الْإِبِلَ بِالْبَقِيعِ فَأَبِيعُ بِالدَّنَانِيرِ وَآخُذُ الدَّرَاهِمَ وَأَبِيعُ بِالدَّرَاهِمِ وَآخُذُ الدَّنَانِيرَ فَقَالَ النَّبِيُّ ﷺ «لَا بَأْسَ إِذَا أَخَذْتُهُمَا بِسِعْرِ يَوْمِهِمَا فَافْتَرَقْتُمَا وَلَيْسَ بَيْنَكُمَا شَيْءٌ»
