Musannaf Ibn Abi Shayba 37:479

Abu Usama narrated to us, he said: Zakariya narrated to us, from Abu Ishaq, from Abu al-Aliyah Abdullah ibn Salamah al-Hamdani, from Abu Maysarah, he said: A rabble of people will remain who do not recognize a right, and do not denounce a wrong. They will mount one another like the mounting of beasts and cattle.
