It was narrated that 'Abdullah (رضي الله عنه) said:

The Messenger of Allah (ﷺ) said: "There will be in charge of your affairs after I am gone men who will extinguish the sunnah and introduce bid'ah (innovation); they will delay the prayer from its proper time.” Ibn Mas'ood (رضي الله عنه) said: O Messenger of Allah, what should I do if I live to see them? He said: "O Ibn Umm 'Abd, there is no obedience to the one who disobeys Allah.” And he said it three times.
