HTI Press. Abdillah, a representative of Hizb ut Tahrir-Batam, confirmed that nationalism is dangerous for Muslim beliefs. Nationalism is a sense of identity with the nation. It is similar to tribalism. It is this nationalism that is forbidden by Islam. Nationalism is also politically dangerous. It has weakened the unity of Muslim Ummah. They are now split into more then 70 nation states after being united under one leader, one flag and one state - Islamic Khilafah. They are currently in conflict each other as Abdullah conveyed that message in front of 3,000 onlookers in Lapangan Tumenggung Abdul Jamal Batam.
