I will not get into important details; however, in a Total War scenario, the Muslim world collectively will not be able to stand in front of the U.S., let alone the entire West combined.
Let's say KSA is attacked tomorrow by the combined forces of the West; how will you fly there? Even the Russian aviation department is telling the pilots to fix it on their own and fly. Let's go further; 90% of your hardware is from the West. How will you replenish lost hardware like fighter jets, missiles, and ships? You do realize to fight the Houthi; the KSA regime is paying the Americans for satellite information and collecting a handsome amount?
The critical raw material is controlled by the West globally. Even Japan, during WWII, first occupied Asian territories and solidified its stronghold because they knew back then they could not war without access to raw materials and logistics to move it. But, unfortunately, the Islamic World failed in strategizing even in this basic concept; even the Pakistan Army held so hear would be useless to have a three-week conflict.
The Islamic World doesn't even have access to high-grade machines and equipment to build complex semiconductors for military hardware, let alone civilian use. Even the Russians were forced to import stolen washing machines to scrap what they could for their tanks. Moreover, unlike the West during the COVID crisis, you cannot make medicines to save your life.
The list is endless, and I suggest you come out of your Islami Jazba phase and understand the ground facts. This is just a tiny sample; going even further in-depth, you would die of shaming being a Muslim in our current time.
P.S.: Your nuclear-armed army put up their hands and surrendered in one call from Secretary of State Collin Powell, a house negro. After the end of this call, you should have just nuked yourselves.
