Sahih Bukhari Volume 9, Book 92, Hadith 7091

حَدَّثَنَا مُعَاذُ بْنُ فَضَالَةَ، حَدَّثَنَا هِشَامٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ سَأَلُوا النَّبِيَّ صلى الله عليه وسلم حَتَّى أَحْفَوْهُ بِالْمَسْأَلَةِ، فَصَعِدَ النَّبِيُّ صلى الله عليه وسلم ذَاتَ يَوْمٍ الْمِنْبَرَ فَقَالَ ‏"‏ لاَ تَسْأَلُونِي عَنْ شَىْءٍ إِلاَّ بَيَّنْتُ لَكُمْ ‏"‏‏.‏ فَجَعَلْتُ أَنْظُرُ يَمِينًا وَشِمَالاً، فَإِذَا كُلُّ رَجُلٍ رَأْسُهُ فِي ثَوْبِهِ يَبْكِي، فَأَنْشَأَ رَجُلٌ كَانَ إِذَا لاَحَى يُدْعَى إِلَى غَيْرِ أَبِيهِ فَقَالَ يَا نَبِيَّ اللَّهِ مَنْ أَبِي فَقَالَ ‏"‏ أَبُوكَ حُذَافَةُ ‏"‏‏.‏ ثُمَّ أَنْشَأَ عُمَرُ فَقَالَ رَضِينَا بِاللَّهِ رَبًّا، وَبِالإِسْلاَمِ دِينًا، وَبِمُحَمَّدٍ رَسُولاً، نَعُوذُ بِاللَّهِ مِنْ سُوءِ الْفِتَنِ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ مَا رَأَيْتُ فِي الْخَيْرِ وَالشَّرِّ كَالْيَوْمِ قَطُّ، إِنَّهُ صُوِّرَتْ لِي الْجَنَّةُ وَالنَّارُ حَتَّى رَأَيْتُهُمَا دُونَ الْحَائِطِ ‏"‏‏.‏ قَالَ قَتَادَةُ يُذْكَرُ هَذَا الْحَدِيثُ عِنْدَ هَذِهِ الآيَةِ ‏{‏يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَسْأَلُوا عَنْ أَشْيَاءَ إِنْ تُبْدَ لَكُمْ تَسُؤْكُمْ‏}‏

Narrated By Anas : The people started asking the Prophet too many questions importunately. So one day he ascended the pulpit and said, "You will not ask me any question but I will explain it to you." I looked right and left, and behold, every man was covering his head with his garment and weeping. Then got up a man who, whenever quarrelling with somebody, used to be accused of not being the son of his father. He said, "O Allah's Apostle! Who is my father?" The Prophet replied, "Your father is Hudhaifa." Then 'Umar got up and said, "We accept Allah as our Lord, Islam as our religion and Muhammad as our Apostle and we seek refuge with Allah from the evil of afflictions." The Prophet said, " I have never seen the good and bad like on this day. No doubt, Paradise and Hell was displayed in front of me till I saw them in front of that wall," Qatada said: This Hadith used to be mentioned as an explanation of this Verse: 'O you who believe! Ask not questions about things which, if made plain to you, may cause you trouble.' (5.101)
