Musnad Ahmad Hadith 12819

It is narrated from Anas (may Allah be pleased with him) that some people became Muslim, but the climate of Madinah did not suit them. The Prophet (ﷺ) said to them, "If you go to our camels and drink their milk, perhaps you will recover." So they did so, but when they became healthy, they reverted to disbelief and turned back to kufr. They killed the Muslim shepherd of the Prophet (ﷺ) and drove away the camels of the Prophet (ﷺ). The Prophet (ﷺ) sent companions after them, they were captured and brought before the Prophet (ﷺ). The Prophet (ﷺ) ordered their hands and feet to be cut off from opposite sides, their eyes to be branded with hot irons, and they were left in rocky areas until they died.
