Pakistan army and establishment had its mistakes for which they paid for. Pakistan didn’t implement Shariah and strayed away from Islam so it paid the consequences of such action.
As for losing the war:
Allah tests Muslims:
“Surely We will test you with a bit of fear and hunger, and loss in wealth and lives and fruits, and give good tidings to the patient.”
-Quran 2:155
A true Muslim is tested with countless trails. The Muslims in the Battle of Uhud faced trials and tribulations.
But rest reassured. The Quran and Authentic Hadith give us guidance and tell us about what’s going to happen. As for your idol worshippers, we are already told about our victory against you. Just wait for the time to come and you’ll see.
You idol worshipers already worship man, animals and rocks. You guys are already set to be Dajjal’s army. I could craft a clay sculpture with my bare hands and you idol worshippers would worship it. You are Dajjal’s army already. You guys suck off Zionists who see Dajjal as their true Messiah. You’re worse than Dajjal’s army. You guys are slaves of Dajjal’s army (Zionists).
Don’t worry. When Isa (Jesus) PBUH comes down to the earth, Dajjal and his army will be defeated.
