باب أَيَّامِ الْجَاهِلِيَّةِ
Sahih al-Bukhari 3843

Narrated Ibn `Umar:

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.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، أَخْبَرَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ كَانَ [place]أَهْلُ الْجَاهِلِيَّةِ [/place]يَتَبَايَعُونَ لُحُومَ الْجَزُورِ إِلَى حَبَلِ الْحَبَلَةِ، قَالَ وَحَبَلُ الْحَبَلَةِ أَنْ تُنْتَجَ النَّاقَةُ مَا فِي بَطْنِهَا، ثُمَّ تَحْمِلَ الَّتِي نُتِجَتْ، فَنَهَاهُمُ النَّبِيُّ صلى الله عليه وسلم عَنْ ذَلِكَ‏.‏
