Sunnan Abu Dawud Collection: ::Book Number 38:: Hadith # 4356
Narrated Abdullah ibn Umar: Some people raided the camels of the Prophet (peace_be_upon_him), drove them off, and apostatised. They killed the herdsman of the Apostle of Allah (peace_be_upon_him) who was a believer. He (the Prophet) sent (people) in pursuit of them and they were caught. He had their hands and feet cut off, and their eyes put out. The verse regarding fighting against Allah and His Prophet (peace_be_upon_him) was then revealed. These were the people about whom Anas ibn Malik informed al-Hajjaj when he asked him.
