The besic roots of Islam are truth, honesty and trustworthiness.
During Muslim occupation of Spain (711-1236) hundreds of mosques were made without Spanish people approval. Even today Muslim are proud of that architecture. But were they legit, no they were made by force on occupied territory. When Christian's took back Spain in 1492, they killed all men and sealed all mosques. This happens when lands are occupied.
India's case is similar, it's their time & not our right. Akbar e Azam is no more. They will do what they think they should do.
Are we honest in demanding back any of Muslim property , we should ask ourself acc to Islam.
Do not occupy others properties.
Just be thankful that we have Pakistan, thanks to Allama Iqbal and QA M.A.Jinnah. Therefore Pakistan isn't an occupied property.
