It is narrated from Sayyiduna Samurah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Some people who had been with me will come to me (at the Pond). Then, when they raise their heads towards me, they will be pulled away before reaching me, and I will say: 'O my Lord, these are my companions, my companions?' It will be said: 'You do not know what new things they invented after you.'"
