Sunan Ibn Majah 4061

It was narrated from Nafi’ that a man came to Ibn ‘Umar and said:“So-and-so sends his Salam to you.” He said: “I have heard that he has introduced innovations (into Islam). If he has indeed introduced innovations, then do not convey my Salam to him, for I heard the Messenger of Allah (ﷺ) say: ‘There will be among my nation – or among this nation – transformations, the earth collapsing, and Qadhf.’ That was concerning Ahlul-Qadar.”
