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.”
