Narrated Anas:

The climate of Medina did not suit some people, so the Prophet ordered them to follow his shepherd, i.e. his camels, and drink their milk and urine (as a medicine). So they followed the shepherd that is the camels and drank their milk and urine till their bodies became healthy. Then they killed the shepherd and drove away the camels. When the news reached the Prophet he sent some people in their pursuit. When they were brought, he cut their hands and feet and their eyes were branded with heated pieces of iron.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ ـ رضى الله عنه ـ أَنَّ نَاسًا، اجْتَوَوْا فِي الْمَدِينَةِ فَأَمَرَهُمُ النَّبِيُّ ﷺ أَنْ يَلْحَقُوا بِرَاعِيهِ ـ يَعْنِي الإِبِلَ ـ فَيَشْرَبُوا مِنْ أَلْبَانِهَا وَأَبْوَالِهَا، فَلَحِقُوا بِرَاعِيهِ فَشَرِبُوا مِنْ أَلْبَانِهَا وَأَبْوَالِهَا، حَتَّى صَلَحَتْ أَبْدَانُهُمْ فَقَتَلُوا الرَّاعِيَ وَسَاقُوا الإِبِلَ، فَبَلَغَ النَّبِيَّ ﷺ فَبَعَثَ فِي طَلَبِهِمْ، فَجِيءَ بِهِمْ فَقَطَعَ أَيْدِيَهُمْ وَأَرْجُلَهُمْ، وَسَمَرَ أَعْيُنَهُمْ. قَالَ قَتَادَةُ فَحَدَّثَنِي مُحَمَّدُ بْنُ سِيرِينَ أَنَّ ذَلِكَ كَانَ قَبْلَ أَنْ تَنْزِلَ الْحُدُودُ.
