Sahih Bukhari | Volume 8 | Hadith Number 592
Narrated by Asma 'bint Abu Bakr
The Prophet 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."
