Anas bin Malik (RA) 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 ( صلی اللہ علیہ وسلم ) 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).
