Shayban bin 'Abdur Rahman شيبان بن عبد الرحمن النحوي أبو معاوية · The Book on Virtues of Jihad

"The Messenger of Allah (ﷺ) was asked about a man who fights out of bravery, one who fights out of protection (for himself or others), and one who fought to be seen. Which of them is in the cause of Allah ? He said: 'Whoever fought so that the Word of Allah is supreme, then he is in Allah's cause.'" There is something on this topic from 'Umar. This Hadith is Hasan Sahih.
