Narrated Anas: Once the people started asking Allah's Apostle questions, and they asked so many questions that he became angry and ascended the pulpit and said, "I will answer whatever questions you may ask me today." I looked right and left and saw everyone covering his face with his garment and weeping. Behold! There was a man who, on quarreling with the people, used to be called as a son of a person other than h is father. He said, "O Allah's Apostle! Who is my father?" The Prophet replied, "Your father is Hudhaifa." And then `Umar got up and said, "We accept Allah as our Lord, and Islam as (our) religion, and Muhammad as (our) Apostle; and we seek refuge with Allah from the afflictions." Allah's Apostle said, " I have never seen a day like today in its good and its evil for Paradise and the Hell Fire were displayed in front of me, till I saw them just beyond this wall." Qatada, when relating this Hadith, used to mention the following Verse:-- 'O you who believe! Ask not questions about things which, If made plain to you, May cause you trouble. (5.101)
