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 his 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 ﷺ 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)

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا هِشَامٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ ـ رضى الله عنه سَأَلُوا رَسُولَ اللَّهِ ﷺ حَتَّى أَحْفَوْهُ الْمَسْأَلَةَ فَغَضِبَ فَصَعِدَ الْمِنْبَرَ فَقَالَ " لاَ تَسْأَلُونِي الْيَوْمَ عَنْ شَىْءٍ إِلاَّ بَيَّنْتُهُ لَكُمْ ". فَجَعَلْتُ أَنْظُرُ يَمِينًا وَشِمَالاً، فَإِذَا كُلُّ رَجُلٍ لاَفٌّ رَأْسَهُ فِي ثَوْبِهِ يَبْكِي، فَإِذَا رَجُلٌ كَانَ إِذَا لاَحَى الرِّجَالَ يُدْعَى لِغَيْرِ أَبِيهِ فَقَالَ يَا رَسُولَ اللَّهِ مَنْ أَبِي قَالَ " حُذَافَةُ "، ثُمَّ أَنْشَأَ عُمَرُ فَقَالَ رَضِينَا بِاللَّهِ رَبًّا، وَبِالإِسْلاَمِ دِينًا، وَبِمُحَمَّدٍ ﷺ رَسُولاً، نَعُوذُ بِاللَّهِ مِنَ الْفِتَنِ. فَقَالَ رَسُولُ اللَّهِ ﷺ " مَا رَأَيْتُ فِي الْخَيْرِ وَالشَّرِّ كَالْيَوْمِ قَطُّ، إِنَّهُ صُوِّرَتْ لِي الْجَنَّةُ وَالنَّارُ حَتَّى رَأَيْتُهُمَا وَرَاءَ الْحَائِطِ ". وَكَانَ قَتَادَةُ يَذْكُرُ عِنْدَ الْحَدِيثِ هَذِهِ الآيَةَ {يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَسْأَلُوا عَنْ أَشْيَاءَ إِنْ تُبْدَ لَكُمْ تَسُؤْكُمْ}.
