Sahih al-Bukhari 5590
Narrated Abu 'Amir or Abu Malik Al-Ash'ari:
that he heard the Prophet (ﷺ) saying, "From among my followers there will 
     be some people who will consider illegal sexual intercourse, the 
     wearing of silk, the drinking of alcoholic drinks and the use of 
     musical instruments, as lawful. And there will be some people who will
     stay near the side of a mountain and in the evening their shepherd 
     will come to them with their sheep and ask them for something, but 
     they will say to him, 'Return to us tomorrow.' Allah will destroy them
     during the night and will let the mountain fall on them, and He will 
     transform the rest of them into monkeys and pigs and they will remain 
     so till the Day of Resurrection."
وَقَالَ هِشَامُ بْنُ عَمَّارٍ حَدَّثَنَا صَدَقَةُ بْنُ خَالِدٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ يَزِيدَ بْنِ جَابِرٍ، حَدَّثَنَا عَطِيَّةُ بْنُ قَيْسٍ الْكِلاَبِيُّ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ غَنْمٍ الأَشْعَرِيُّ، قَالَ حَدَّثَنِي أَبُو عَامِرٍ ـ أَوْ أَبُو مَالِكٍ ـ الأَشْعَرِيُّ وَاللَّهِ مَا كَذَبَنِي سَمِعَ النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏
"‏ لَيَكُونَنَّ مِنْ أُمَّتِي أَقْوَامٌ يَسْتَحِلُّونَ الْحِرَ وَالْحَرِيرَ وَالْخَمْرَ وَالْمَعَازِفَ، وَلَيَنْزِلَنَّ أَقْوَامٌ إِلَى جَنْبِ عَلَمٍ يَرُوحُ عَلَيْهِمْ بِسَارِحَةٍ لَهُمْ، يَأْتِيهِمْ ـ يَعْنِي الْفَقِيرَ ـ لِحَاجَةٍ فَيَقُولُوا ارْجِعْ إِلَيْنَا غَدًا‏.‏ فَيُبَيِّتُهُمُ اللَّهُ وَيَضَعُ الْعَلَمَ، وَيَمْسَخُ آخَرِينَ قِرَدَةً وَخَنَازِيرَ إِلَى يَوْمِ الْقِيَامَةِ ‏"‏‏.‏
