Fight your soul.
You are not ready for any external battle if you haven’t fought the battles within; the battle against kufr, doubt, hypocrisy, greed, jealousy, hate, malice…
Go inside and fight your soul!
“And by the soul and He Who perfected it. Then inspired it to understand what is wrong and (what is) right for it. Indeed he succeeds who purifies it. And indeed he fails who corrupts it”.
Quran chapter 91 verses 7-10.
