All of them failed. Muslims right now are more divided than ever.
The Gulf monarchies were closer back in the 90s to the 2010s. Remember what happened then? Qatar blockade,war on Yemen,some supported it,some didn't. Saudi Arabia and UAE now getting closer with Israel. Qatar getting closer with Turkey.
Jordan was very close with Iraq,then Saddam was toppled and now Iraq is mostly a Shia Iranian protectorate.
Pakistan and Bangladesh are supposed to be friends now,but how close are they really?
Pakistan and Afghanistan,how close are they? Morocco and Algeria against each other. Half of Libya is pro-Turkish and the other half is pro-Egyptian. Morocco won't recognize the Sahrawi Republic.
Indonesia and Malaysia,are they cooperating with each other?
Albania and Kosovo have dreams of EU. Iran and Azerbaijan are not in good terms. Turkey wants to lead the Turkic countries AND the muslim world.
I honestly think you know too little about the Muslim mindset to even begin to speak about this.
Forget all the Zio-US imposed and supported Muslim regimes and the current world order that has existed for centuries which will soon be toppled.
Once the world moves into a "multi-polar" one next decade then HUGE changes will occur in the Muslim world as the government's then will be more representative of the people and aligned to both their people's and wider Muslim interests.
Muslims will form one of the 3 great power centres of the world and it won't be just about USA and China in a "multi-polar" world that is about to come soon.
