"I will say those people are from me. It will be said, 'You do not know what changes and new things they did after you.' Then I will say, 'Far removed (from mercy), far removed (from mercy), those who changed (the religion) after me!"

I heard Allah's Messenger (ﷺ) say in the company of his Companions: I would be on the Cistern waiting for those who would be coming to me from amongst you. By Allah, some persons would be prevented from coming to me, and I would say: My Lord, they are my followers and people of my Umma. And He would say,: You don't know what they did after you; they had been constantly turning back on their heels (from their religion).

The Prophet (ﷺ) said, "I am your predecessor at the Lake-Fount, and some of you will be brought in front of me till I will see them and then they will be taken away from me and I will say, 'O Lord, my companions!' It will be said, 'You do not know what they did after you had left.'

The Prophet (ﷺ) said, "I will be standing at the Lake-Fount so that I will see whom among you will come to me; and some people will be taken away from me, and I will say, 'O Lord, (they are) from me and from my followers.' Then it will be said, 'Did you notice what they did after you? By Allah, they kept on turning on their heels (turned as renegades).' " The sub-narrator, Ibn Abi Mulaika said, "O Allah, we seek refuge with You from turning on our heels, or being put to trial in our religion."

But whatever Hudhaifah narrates to you, then believe him, and whatever 'Abdullah teaches you to recite, then recite it."
