The climate of Medina did not suit some people, so the Prophet ﷺ 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 ﷺ 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. (Using translation from Bukhārī 5686)
أَنَّ رَهْطًا مِنْ عُرَيْنَةَ أَتَوَا النَّبِيَّ ﷺ فَقَالُوا إِنَّا قَدِ اجْتَوَيْنَا الْمَدِينَةَ وَعَظُمَتْ بُطُونُنَا وَارْتَهَسَتْ أَعْضَادُنَا فَأَمَرَهُمُ النَّبِيُّ ﷺ أَنْ يَلْحَقُوا بِرَاعِي الْإِبِلِ فَيَشْرَبُوا مِنْ أَلْبَانِهَا وَأَبْوَالِهَا فَلَحِقُوا بِرَاعِي الْإِبِلِ فَشَرِبُوا مِنْ أَبْوَالِهَا وَأَلْبَانِهَا حَتَّى صَلُحَتْ بُطُونُهُمْ وَأَبْدَانُهُمْ ثُمَّ قَتَلُوا الرَّاعِيَ وَسَاقُوا الْإِبِلَ فَبَلَغَ ذَلِكَ النَّبِيَّ ﷺ فَبَعَثَ فِي طَلَبِهِمْ فَجِيءَ بِهِمْ فَقَطَعَ أَيْدِيَهُمْ وَأَرْجُلَهُمْ وَسَمَرَ أَعْيُنَهُمْ قَالَ قَتَادَةُ فَحَدَّثَنِي مُحَمَّدُ بْنُ سِيرِينَ أَنَّ ذَلِكَ قَبْلَ أَنْ تَنْزِلَ الْحُدُودُ
