Anas said, "Some people of ʿUkl or ʿUraina tribe came to Medina and its climate did not suit them. So the Prophet ﷺ ordered them to go to the herd of (Milch) camels and to drink their milk and urine (as a medicine). So they went as directed and after they became healthy, they killed the shepherd of the Prophet and drove away all the camels. The news reached the Prophet ﷺ early in the morning and he sent (men) in their pursuit and they were captured and brought at noon. He then ordered to cut their hands and feet (and it was done), and their eyes were branded with heated pieces of iron, They were put in 'Al-Harra' and when they asked for water, no water was given to them." Abu Qilaba said, "Those people committed theft and murder, became infidels after embracing Islam and fought against Allah and His Apostle ."  

قَدِمَ أُنَاسٌ مِنْ عُكْلٍ أَوْ عُرَيْنَةَ فَاجْتَوَوُا الْمَدِينَةَ فَأَمَرَهُمُ النَّبِيُّ ﷺ بِلِقَاحٍ وَأَنْ يَشْرَبُوا مِنْ أَبْوَالِهَا وَأَلْبَانِهَا فَانْطَلَقُوا فَلَمَّا صَحُّوا قَتَلُوا رَاعِيَ النَّبِيِّ ﷺ وَاسْتَاقُوا النَّعَمَ فَجَاءَ الْخَبَرُ فِي أَوَّلِ النَّهَارِ فَبَعَثَ فِي آثَارِهِمْ فَلَمَّا ارْتَفَعَ النَّهَارُ جِيءَ بِهِمْ فَأَمَرَ فَقَطَعَ أَيْدِيَهُمْ وَأَرْجُلَهُمْ وَسُمِرَتْ أَعْيُنُهُمْ وَأُلْقُوا فِي الْحَرَّةِ يَسْتَسْقُونَ فَلاَ يُسْقَوْنَ قَالَ أَبُو قِلاَبَةَ فَهَؤُلاَءِ سَرَقُوا وَقَتَلُوا وَكَفَرُوا بَعْدَ إِيمَانِهِمْ وَحَارَبُوا اللَّهَ وَرَسُولَهُ  

Prior to the construction of the mosque, the Prophet ﷺ offered the prayers at sheep-folds.  

كَانَ النَّبِيُّ ﷺ يُصَلِّي قَبْلَ أَنْ يُبْنَى الْمَسْجِدُ فِي مَرَابِضِ الْغَنَمِ
