Musannaf Ibn Abi Shayba 37:466

Waki’ narrated to us, from Shu’bah, from Qatadah, from Waqi’ ibn Sahban, from Tarif ibn Yazid ibn Tarif, from Abu Musa, who said: "Indeed, before the Hour, there are days in which ignorance will descend and knowledge will be lifted, until a man will stand up to his mother and strike her with the sword out of ignorance."
