Sunnan Abu Dawud Collection: ::Book Number 14:: Hadith # 2533
Narrated AbuSalam: AbuSalam reported on the authority of a man from the companion of the Prophet (peace_be_upon_him). He said: We attacked a tribe of Juhaynah. A man from the Muslims pursued a man of them, and struck him but missed him. He struck himself with the sword. The Apostle of Allah (peace_be_upon_him) said: Your brother, O group of Muslims. The people hastened towards him, but found him dead. The Apostle of Allah (peace_be_upon_him) wrapped him with his clothes and his blood, and offered (funeral) prayer for him and buried him. They said: Apostle of Allah, is he a martyr? He said: Yes, and I am witness to him.
