Sahih al-Bukhari · Book 63: Merits of the Helpers in Madinah (Ansaar) · Al-Qasama in the Pre-Islamic Period of Ignorance
Narrated `Amr bin Maimun:
حَدَّثَنَا نُعَيْمُ بْنُ حَمَّادٍ ، حَدَّثَنَا هُشَيْمٌ ، عَنْ حُصَيْنٍ ، عَنْ عَمْرِو بْنِ مَيْمُونٍ ، قَالَ رَأَيْتُ فِي الْجَاهِلِيَّةِ قِرْدَةً اجْتَمَعَ عَلَيْهَا قِرَدَةٌ قَدْ زَنَتْ، فَرَجَمُوهَا فَرَجَمْتُهَا مَعَهُمْ.
During the pre-lslamic period of ignorance I saw a she-monkey surrounded by a number of monkeys. They were all stoning it, because it had committed illegal sexual intercourse. I too, stoned it along with them.
