It is narrated from Hazrat Aisha that I heard the Prophet (peace be upon him) saying: I will wait for those among you who will come to me at the Pond of Kawthar. Some people will be prevented from coming to me. I will say, "O Lord! These are my followers." It will be said to me, "You do not know what deeds they did after you; they kept turning back on their heels continuously."
