In the pre-lslamic period of ignorance the people used to bargain with the meat of camels on the principle of Habal-al-Habala which meant the sale of a she-camel that would be born by a she-camel that had not yet been born. The Prophet ﷺ forbade them such a transaction.

كَانَ أَهْلُ الْجَاهِلِيَّةِ يَتَبَايَعُونَ لُحُومَ الْجَزُورِ إِلَى حَبَلِ الْحَبَلَةِ قَالَ وَحَبَلُ الْحَبَلَةِ أَنْ تُنْتَجَ النَّاقَةُ مَا فِي بَطْنِهَا ثُمَّ تَحْمِلَ الَّتِي نُتِجَتْ فَنَهَاهُمُ النَّبِيُّ ﷺ 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. Messenger of Allah ﷺ forbade them that (this transaction).

كَانَ أَهْلُ الْجَاهِلِيَّةِ يَتَبَايَعُونَ لَحْمَ الْجَزُورِ إِلَى حَبَلِ الْحَبَلَةِ وَحَبَلُ الْحَبَلَةِ أَنْ تُنْتَجَ النَّاقَةُ ثُمَّ تَحْمِلَ الَّتِي نُتِجَتْ فَنَهَاهُمْ رَسُولُ اللَّهِ ﷺ عَنْ ذَلِكَ

[AI] During the time of Jahiliyyah (pre-Islamic ignorance), people used to sell the meat of a pregnant camel along with its fetus and the camel that would produce it. The Messenger of Allah ﷺ forbade them from doing so.

كَانَ أَهْلُ الْجَاهِلِيَّةِ يَبِيعُونَ لَحْمَ الْجَزُورِ بِحَبَلِ حَبَلَةٍ وَحَبَلُ حَبَلَةٍ تُنْتَجُ النَّاقَةُ مَا فِي بَطْنِهَا ثُمَّ تَحْمِلُ الَّتِي تُنْتَجُهُ فَنَهَاهُمْ رَسُولُ اللهِ ﷺ عَنْ ذَلِكَ
