Alama Iqbal said:

Aik ho muslim haram ki pasbani kai liyay
Neel kai sahil ta bukhak kashghar

That is Pan-Islamic Idea based on Khilafat

Again he said:

Na turani rahai baqi, na Irani, na Afghani ( I forgot the first verse )

That is Pan-Islamic Idea


Jamal ud Din Afghani was also of Pan-Islamic ideas. He wanted all the Muslims to unite.

Only Central Asian States doesn't suit for me as a Pan-Islamic idea.

Rest: I might be correct, I might be wrong !
