Narrated 'Amr bin Maimun:

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.

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.
