Sahih Bukhari Volume 7, Book 74, Hadith 5592

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 ‏"‏‏

Narrated By Abu 'Amir or Abu Malik Al-Ash'ari : That he heard the Prophet 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."
