Fighting to elevate the Word of God is what is considered for His sake
A man came to the Prophet ﷺ and said, "A man fights for pride and haughtiness another fights for bravery, and another fights for showing off; which of these (cases) is in Allah's Cause?" The Prophet ﷺ said, "The one who fights that Allah's Word (Islam) should be superior, fights in Allah's Cause."
جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ: الرَّجُلُ يُقَاتِلُ حَمِيَّةً وَيُقَاتِلُ شَجَاعَةً وَيُقَاتِلُ رِيَاءً، فَأَىُّ ذَلِكَ فِي سَبِيلِ اللَّهِ؟ قَالَ: «مَنْ قَاتَلَ لِتَكُونَ كَلِمَةُ اللَّهِ هِيَ الْعُلْيَا فَهْوَ فِي سَبِيلِ اللَّهِ۔»
