حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، - وَاللَّفْظُ لِزُهَيْرٍ - قَالاَ حَدَّثَنَا يَحْيَى، - وَهُوَ الْقَطَّانُ - عَنْ عُبَيْدِ اللَّهِ، أَخْبَرَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، قَالَ كَانَ أَهْلُ الْجَاهِلِيَّةِ يَتَبَايَعُونَ لَحْمَ الْجَزُورِ إِلَى حَبَلِ الْحَبَلَةِ ‏.‏ وَحَبَلُ الْحَبَلَةِ أَنْ تُنْتَجَ النَّاقَةُ ثُمَّ تَحْمِلَ الَّتِي نُتِجَتْ فَنَهَاهُمْ رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ ذَلِكَ ‏.‏

Ibn 'Umar (Allah be pleased with them) reported that the people of pre-Islamic days used to sell the meat of the slaughtered camel up to habal al-habala. And habal al-habala implies that a she-camel should give birth and then the (born one should grow young) and become pregnant. Allah's Messenger (PBUH) forbade them that (this transaction).
