Narrated Anas bin Malik:

The Prophet came out after the sun had declined and offered the Zuhr prayer (in congregation). After finishing it with Taslim, he stood on the pulpit and mentioned the Hour and mentioned there would happen great events before it. Then he said, "Whoever wants to ask me any question, may do so, for by Allah, you will not ask me about anything but I will inform you of its answer as long as I am at this place of mine." On this, the Ansar wept violently, and Allah's Apostle kept on saying, "Ask Me! " Then a man got up and asked, ''Where will my entrance be, O Allah's Apostle?" The Prophet ﷺ said, "(You will go to) the Fire." Then 'Abdullah bin Hudhaifa got up and asked, "Who is my father, O Allah's Apostle?" The Prophet replied, "Your father is Hudhaifa." The Prophet then kept on saying (angrily), "Ask me! Ask me!" 'Umar then knelt on his knees and said, "We have accepted Allah as our Lord and Islam as our religion and Muhammad as an Apostle." Allah's Apostle became quiet when 'Umar said that. Then Allah's Apostle ﷺ said, "By Him in Whose Hand my life is, Paradise and Hell were displayed before me across this wall while I was praying, and I never saw such good and evil as I have seen today."

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ،. وَحَدَّثَنِي مَحْمُودٌ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، أَخْبَرَنِي أَنَسُ بْنُ مَالِكٍ ـ رضى الله عنه. أَنَّ النَّبِيَّ ﷺ خَرَجَ حِينَ زَاغَتِ الشَّمْسُ فَصَلَّى الظُّهْرَ فَلَمَّا سَلَّمَ قَامَ عَلَى الْمِنْبَرِ فَذَكَرَ السَّاعَةَ، وَذَكَرَ أَنَّ بَيْنَ يَدَيْهَا أُمُورًا عِظَامًا ثُمَّ قَالَ " مَنْ أَحَبَّ أَنْ يَسْأَلَ عَنْ شَىْءٍ فَلْيَسْأَلْ عَنْهُ، فَوَاللَّهِ لاَ تَسْأَلُونِي عَنْ شَىْءٍ إِلاَّ أَخْبَرْتُكُمْ بِهِ، مَا دُمْتُ فِي مَقَامِي هَذَا ". قَالَ أَنَسٌ فَأَكْثَرَ النَّاسُ الْبُكَاءَ، وَأَكْثَرَ رَسُولُ اللَّهِ ﷺ أَنْ يَقُولَ " سَلُونِي ". فَقَالَ أَنَسٌ فَقَامَ إِلَيْهِ رَجُلٌ فَقَالَ أَيْنَ مَدْخَلِي يَا رَسُولَ اللَّهِ قَالَ " النَّارُ ". فَقَامَ عَبْدُ اللَّهِ بْنُ حُذَافَةَ فَقَالَ مَنْ أَبِي يَا رَسُولَ اللَّهِ قَالَ " أَبُوكَ حُذَافَةُ ". قَالَ ثُمَّ أَكْثَرَ أَنْ يَقُولَ " سَلُونِي سَلُونِي ". فَبَرَكَ عُمَرُ عَلَى رُكْبَتَيْهِ فَقَالَ رَضِينَا بِاللَّهِ رَبًّا، وَبِالإِسْلاَمِ دِينًا، وَبِمُحَمَّدٍ ﷺ رَسُولاً. قَالَ فَسَكَتَ رَسُولُ اللَّهِ ﷺ حِينَ قَالَ عُمَرُ ذَلِكَ، ثُمَّ قَالَ رَسُولُ اللَّهِ ﷺ " وَالَّذِي نَفْسِي بِيَدِهِ لَقَدْ عُرِضَتْ عَلَىَّ الْجَنَّةُ وَالنَّارُ آنِفًا فِي عُرْضِ هَذَا الْحَائِطِ وَأَنَا أُصَلِّي، فَلَمْ أَرَ كَالْيَوْمِ فِي الْخَيْرِ وَالشَّرِّ ".
