Narrated Abu Hurairah (RA):

The Prophet (ﷺ) forbade the sale of what is in the womb of a she-camel, and the semen that is in the body of a male-camel. [Reported by al-Bazzar and there is weakness in its Isnad (chain of narrators)].

وَعَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-نَهَى عَنْ بَيْعِ اَلْمَضَامِينِ, وَالْمَلَاقِيحِ } رَوَاهُ اَلْبَزَّارُ, وَفِي إِسْنَادِ [ هِ ] ضَعْفٌ [1]‏ .‏
