Narrated Abdullah ibn Umar:I used to sell camels at al-Baqi for dinars and take dirhams for them, and sell for dirhams and take dinars for them. I would take these for these and give these for these. I went to the Messenger of Allah (ﷺ) who was in the house of Hafsah. I said: Messenger of Allah , take it easy, I shall ask you (a question): I sell camels at al-Baqi'. I sell (them) for dinars and take dirhams and I sell for dirhams and take dinars. I take these for these, and give these for these. The Messenger of Allah (ﷺ) then said: There is no harm in taking them at the current rate so long as you do not separate leaving something to be settled.
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، وَمُحَمَّدُ بْنُ مَحْبُوبٍ، - الْمَعْنَى وَاحِدٌ - قَالاَ حَدَّثَنَا حَمَّادٌ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عُمَرَ، قَالَ كُنْتُ أَبِيعُ الإِبِلَ بِالْبَقِيعِ فَأَبِيعُ بِالدَّنَانِيرِ وَآخُذُ الدَّرَاهِمَ وَأَبِيعُ بِالدَّرَاهِمِ وَآخُذُ الدَّنَانِيرَ آخُذُ هَذِهِ مِنْ هَذِهِ وَأُعْطِي هَذِهِ مِنْ هَذِهِ فَأَتَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم وَهُوَ فِي بَيْتِ حَفْصَةَ فَقُلْتُ يَا رَسُولَ اللَّهِ رُوَيْدَكَ أَسْأَلُكَ إِنِّي أَبِيعُ الإِبِلَ بِالْبَقِيعِ فَأَبِيعُ بِالدَّنَانِيرِ وَآخُذُ الدَّرَاهِمَ وَأَبِيعُ بِالدَّرَاهِمِ وَآخُذُ الدَّنَانِيرَ آخُذُ هَذِهِ مِنْ هَذِهِ وَأُعْطِي هَذِهِ مِنْ هَذِهِ . فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ بَأْسَ أَنْ تَأْخُذَهَا بِسَعْرِ يَوْمِهَا مَا لَمْ تَفْتَرِقَا وَبَيْنَكُمَا شَىْءٌ " .
