4 Obligation of an Islamic Government and Muslim leader
- Establishment of Prayers and Muslim leader MUST LEAD Jumu'ah prayers or duly appoint his deputy (at least in the Capital)
- Collect Zakat and Ushr and distribute
- Actively encourage good deeds
- Actively prohibit sinning, evil and vulgarity
The first 2 actions are not been politically incorrect and will lead to collection of revenue for poor countries but I don't know any Muslim country doing it. In fact, I am willing to bet that many Muslims reading this may not even know what Ushr means!
Judge Imran Khan and Erdogan or XYZ according to these 4 actions, doesn't mean that these country are Non-Muslims or people are "Non-Muslims" but this is what the Qur'aan demanded of Nabi (Sallallaho Alaihe Wassallam) when he migrated to Madina.
