Sahih Bukhari Volume 8, Book 86, Hadith 6804

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، حَدَّثَنَا الأَوْزَاعِيُّ، حَدَّثَنِي يَحْيَى بْنُ أَبِي كَثِيرٍ، قَالَ حَدَّثَنِي أَبُو قِلاَبَةَ الْجَرْمِيُّ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ قَدِمَ عَلَى النَّبِيِّ صلى الله عليه وسلم نَفَرٌ مِنْ عُكْلٍ، فَأَسْلَمُوا فَاجْتَوَوُا الْمَدِينَةَ، فَأَمَرَهُمْ أَنْ يَأْتُوا إِبِلَ الصَّدَقَةِ، فَيَشْرَبُوا مِنْ أَبْوَالِهَا وَأَلْبَانِهَا، فَفَعَلُوا فَصَحُّوا، فَارْتَدُّوا وَقَتَلُوا رُعَاتَهَا وَاسْتَاقُوا، فَبَعَثَ فِي آثَارِهِمْ فَأُتِيَ بِهِمْ، فَقَطَعَ أَيْدِيَهُمْ وَأَرْجُلَهُمْ وَسَمَلَ أَعْيُنَهُمْ، ثُمَّ لَمْ يَحْسِمْهُمْ حَتَّى مَاتُوا‏

Narrated By Anas : Some people from the tribe of 'Ukl came to the Prophet and embraced Islam. The climate of Medina did not suit them, so the Prophet ordered them to go to the (herd of milch) camels of charity and to drink, their milk and urine (as a medicine). They did so, and after they had recovered from their ailment (became healthy) they turned renegades (reverted from Islam) and killed the shepherd of the camels and took the camels away. The Prophet sent (some people) in their pursuit and so they were (caught and) brought, and the Prophets ordered that their hands and legs should be cut off and that their eyes should be branded with heated pieces of iron, and that their cut hands and legs should not be cauterised, till they die.
