Muwatta Malik 1351

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ بَيْعِ حَبَلِ الْحَبَلَةِ ‏.‏ وَكَانَ بَيْعًا يَتَبَايَعُهُ أَهْلُ الْجَاهِلِيَّةِ كَانَ الرَّجُلُ يَبْتَاعُ الْجَزُورَ 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, may Allah bless him and grant him peace, 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
