Isma'il bin Umayya bin 'Amr إسماعيل بن أمية بن عمرو · Jihad (Kitab Al-Jihad)

Messenger of Allah, tell me about jihad and fighting. He replied: Abdullah ibn Amr, if you fight with endurance seeking from Allah your reward, Allah will resurrect you showing endurance and seeking your reward from Him, but, if you fight for vain show seeking to acquire much, Allah will resurrect you making a vain show and seeking to acquire much. In whatever you fight or are killed, Abdullah ibn Amr, in that state Allah will resurrect you.
