Sahih Muslim — Hadith #13559

Muhammad ibn Hatim narrated to me (saying): Affan ibn Muslim al-Saffar narrated to us (saying): Wuheyb narrated to us (saying): I heard Abdul-Aziz ibn Suhaybi narrating (saying): Anas ibn Malik narrated to us that the Prophet (peace and blessings be upon him) said: "A group of men who were my companions will surely come to me at the pool. When I see them and they are presented to me, they will leave me. I will surely say: 'O my Lord! My little companions! My little companions!' And it will be said to me: 'Indeed, you do not know what they have invented after you!'"
