(21) باب مَنْ قَاتَلَ لِتَكُونَ كَلِمَةُ اللَّهِ هِيَ الْعُلْيَا .
Abu Musa Al-Ash'ari said:
"A Bedouin came to the Messenger of Allah (ﷺ) and said: 'A man fights for fame, or he fights for the spoils of war, or he fights to show off. Who is the one who is fighting in the cause of Allah?' He said: 'The one who fights so that the word of Allah will be supreme is the one who is fighting in the cause of Allah, the Mighty and Sublime.'"
