وَعَن أبي مُوسَى قَالَ: جَاءَ رَجُلٌ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: الرَّجُلُ يُقَاتِلُ لِلْمَغْنَمِ وَالرَّجُلُ يُقَاتِلُ لِلذِّكْرِ وَالرَّجُلُ يُقَاتِلُ لِيُرَى مَكَانُهُ فَمَنْ فِي سَبِيلِ اللَّهِ؟ قَالَ: «مَنْ قَاتَلَ لِتَكُونَ كَلِمَةُ اللَّهِ هِيَ الْعُلْيَا فَهُوَ فِي سَبِيلِ الله»

Abu Musa told that a man came to the Prophet and said, “One man fights for booty, one for the reputation of fighting, and one for his degree to be seen; which of them is in God’s path?” He replied, “The one who fights that God’s word may have preeminence is in God’s path.” (Bukhari and Muslim.)
