I heard the Messenger of Allah (may peace be upon him) say: The first of men (whose case) will be decided on the Day of Judgment will be a man who died as a martyr. He shall be brought (before the Judgment Seat). Allah will make him recount His blessings (i. e. the blessings which He had bestowed upon him) and he will recount them (and admit having enjoyed them in his life). (Then) will Allah say: What did you do (to requite these blessings)? He will say: I fought for Thee until I died as a martyr. Allah will say: You have told a lie. You fought that you might be called a” brave warrior”. And you were called so. (Then) orders will be passed against him and he will be dragged with his face downward and cast into Hell.
(Sahih Muslim Book #020, Hadith #4688)
