Yahya related to me from Malih from Nafi from Abdullah ibn Umar that the Messenger of Allah ﷺ forbade the transaction called habal alhabala. It was a transaction which the people of Jahiliya practised. A man would buy the unborn offspring of the unborn offspring of a she-camel.
أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنْ بَيْعِ حَبَلِ الْحَبَلَةِ وَكَانَ بَيْعًا يَتَبَايَعُهُ أَهْلُ الْجَاهِلِيَّةِ كَانَ الرَّجُلُ يَبْتَاعُ الْجَزُورَ إِلَى أَنْ تُنْتَجَ النَّاقَةُ ثُمَّ تُنْتَجَ الَّتِي فِي بَطْنِهَا
