It's called development, and in 20 years time with good governance with Imran Khan in place and his party, rapid development is going to occur go the next 20 years. Pakistan will likely surpass Indonesia, Malaysia, and Iran within 20 years in most economic indicators. As far as infrastructure is concern Pakistan has the resources and expertise to build world-class infrastructure, Islamabad is an example.
As for surpassing Iran, Iran's economy is heavily sanctioned, if Pakistan experience healthy economic growth with rapid development in infrastructure, education, and other fields Pakistan will likely surpass Iran in most economic indicators including GDP.
As for Malaysia, their current GDP (PPP) is ~445 billion annual, Pakistan's current GDP (PPP) ~$488 billion. Even in GDP (nominal) Pakistan is ahead of Malaysia currently, in 20 years time Pakistan can double it's GDP, under the condition of good governance and stability which an Imran Khan government is likely to bring, and considering his party is economic oriented this is critical. I doubt Malaysia is going to grow as rapidly as Pakistan in the coming 20 years.
As for Indonesia it will likely take more years to catch up to Indonesia in most economic indicators but Pakistan will reach that league within that time frame. Indonesia's GDP (PPP) is ~$1.2 trillion, and Pakistan's is less than half of that at $488 billion.
As for Turkiye, Pakistan could reach Turkey's current GDP (PPP) which is ~1 trillion, in perhaps 30 years time.
Though as I said, Pakistan is likely in 20 years time to surpass most Muslim and Asian countries in most economic indicators still stands, under the conditions I've outlined (good governance and economic policy).
