Narrated Anas: The Prophet said, "Some of my companions will come to me at my Lake Fount, and after I recognize them, they will then be taken away from me, whereupon I will say, 'My companions!' Then it will be said, 'You do not know what they innovated (new things) in the religion after you."

Narrated Anas bin Malik: Allah's Apostle sent for the Ansar and gathered them in a tent and said to them, "Be patient till you meet Allah and His Apostle, and I will be on the lake-Tank (Al-Kauthar).

Hadith Commentary: The meeting with Allah and His Messenger on the Day of Resurrection is indeed true; those who deny it are misguided. This is the very purpose of the present hadith. Sometimes, regarding the spoils of war (mal-e-ghanīmat), the Ansar would feel some discontent, upon which the Prophet (sallallahu alayhi wa sallam) consoled them. The relevance to the chapter heading is established in this way: he said, "You will meet Allah," meaning you will attain the vision of Allah.
