Ayasofya was more analgous to Somnath, which also was a den of corruption and lies. In both cases those houses of worship lost their right to continue on due to their negative political activities.
Ever since 1453, not a single Muslim scholar criticized conversion of Ayasofya to a masjid, furthermore they recognized Mehmet el Fatih as the one praised by prophet Muhammad saws in the famous hadith.
How can the greatest leader of the greatest army commit a mistake of this level? It simply does not follow.
Houses of worship which are used for political means, organizing armies, and as seats of a state, are fair game.
In this same way, Muslim conquerors who demolished Hindu temples only did so when they were used for political activities, illicit activities, or organizing resistance against the ruler.
Generally masajid are not allowed to be used for this purpose by Muslims, but that stipulation does not apply to Christians.
Now what happened to these pawns of Russians and Orthodox defenders, they cry so much for Ayasofya, did they remember how many Turks, Circassians, Tatars, Azeris, and other Muslims were killed by Russians, Armenians, Greeks, Serbs, and Bulgarians?
I understand what you said, but it does not follow with the rest of Allama Iqbal's thought.
He famously said in Tarana e Milli, "Pura Jahan he hamara -The whole world is ours."
Allama Iqbal always praised the revival and spread of Islam. He was a great lover of Muslim ascendancy.
