Anas bin Malik narrated that:

A group of eighty people from 'Ukl came to the Prophet ﷺ, but the climate of Al-Madinah did not suit them and they fell sick. They complained about that to the Messenger of Allah ﷺ and he said: "Why don't you go out with our herdsmen and drink the milk and urine of the camels?" They said: "Yes (we will do that)." They went out and drank some of the (camels') milk and urine, and they recovered. Then they killed the herdsman of the Messenger of Allah ﷺ, so he sent (men after them) and they caught them and brought them back. He had their hands and feet cut off and branded their eyes, and left them in the sun to die.

أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ، قَالَ حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ حَجَّاجٍ الصَّوَّافِ، قَالَ حَدَّثَنَا أَبُو رَجَاءٍ، مَوْلَى أَبِي قِلاَبَةَ قَالَ حَدَّثَنَا أَبُو قِلاَبَةَ، قَالَ حَدَّثَنِي أَنَسُ بْنُ مَالِكٍ، أَنَّ نَفَرًا، مِنْ عُكْلٍ ثَمَانِيَةً قَدِمُوا عَلَى النَّبِيِّ ﷺ فَاسْتَوْخَمُوا الْمَدِينَةَ وَسَقِمَتْ أَجْسَامُهُمْ فَشَكَوْا ذَلِكَ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ " أَلاَ تَخْرُجُونَ مَعَ رَاعِينَا فِي إِبِلِهِ فَتُصِيبُوا مِنْ أَلْبَانِهَا وَأَبْوَالِهَا " . قَالُوا بَلَى . فَخَرَجُوا فَشَرِبُوا مِنْ أَلْبَانِهَا وَأَبْوَالِهَا فَصَحُّوا فَقَتَلُوا رَاعِيَ رَسُولِ اللَّهِ ﷺ فَبَعَثَ فَأَخَذُوهُمْ فَأُتِيَ بِهِمْ فَقَطَّعَ أَيْدِيَهُمْ وَأَرْجُلَهُمْ وَسَمَّرَ أَعْيُنَهُمْ وَنَبَذَهُمْ فِي الشَّمْسِ حَتَّى مَاتُوا .
