Some people were sick and they said, "O Allah's Messenger (ﷺ)! Give us shelter and food. So when they became healthy they said, "The weather of Medina is not suitable for us." So he sent them to Al-Harra with some she-camels of his and said, "Drink of their milk." But when they became healthy, they killed the shepherd of the Prophet (ﷺ) and drove away his camels. The Prophet (ﷺ) sent some people in their pursuit. Then he got their hands and feet cut and their eyes were branded with heated pieces of iron. I saw one of them licking the earth with his tongue till he died.

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.
