Messenger of Allah ﷺ forbade the sale called 'Habal-al-Habala which was a kind of sale practiced in the Pre- Islamic Period of ignorance. One would pay the price of a she-camel which was not born yet would be born by the immediate offspring of an extant 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 تُنْتَجُ الَّتِي فِي بَطْنِهَا  

the Messenger of Allah forbade selling the offspring of the offspring of a pregnant animal (Habal Al-Habalah), which was a transaction practiced by the people of the Jahiliyyah, whereby a man would buy camel to slaughter, but he would wait until the she-camel had produced offspring and the offspring in her belly had then produced offspring.  

أَنَّ النَّبِيَّ ﷺ نَهَى عَنْ بَيْعِ حَبَلِ الْحَبَلَةِ وَكَانَ بَيْعًا يَتَبَايَعُهُ أَهْلُ الْجَاهِلِيَّةِ كَانَ الرَّجُلُ يَبْتَاعُ جَزُورًا إِلَى أَنْ تُنْتَجَ النَّاقَةُ ثُمَّ تُنْتَجَ الَّتِي فِي بَطْنِهَا  

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

(Using translation from Nasāʾī 4625)
