Sahih Muslim | Book 30 | Hadith Number 5823

Narrated by Anas b. Malik
Anas b. Malik reported that something was conveyed to him (the Holy prophet) about his Companions, so he addressed them and said: Paradise and Hell were presented to me and I have never seen the good and evil as (I did) today. And if you were to know you would have wept more and laughed less. He (the narrator) said: There was nothing more burdensome for the Companions of Allah's Messenger (may peace be upon him) than this. They covered their heads and the sound of weeping was heard from them. Then there stood up 'Umar and he said: We are well pleased with Allah as our Lord, with Islam as

our code of life and with Muhammad as our Apostle, and it was at that time that a person stood up and he said: Who is my father? Thereupon he (the Holy Prophet) said: Your father is so and so; and there was revealed the verse: "O you who believe, do not ask about matters which, if they were to be made manifest to you (in terms of law), might cause to you harm"(v. 101).
