Sunan Abi Dawud 4657
سنن أبي داود#4657Sahih‘Imran b. Husain reported the Messenger of Allah (ﷺ) as saying :the best of my people is the generation in which I have been sent, then their immediate followers, then their immediate followers. Allah knows best whether he mentioned the third or not. After them will be people who will give testimony without being asked, who will make vows which they do not fulfill, who will be treacherous and not to be trusted, among whom fatness will appear
