In Arabic culture, a Majlis-ash-Shura ( Arabic : ÙØ¬ÙØ³ Ø§ÙØ´ÙØ±Ù ââ) is an advisory council or consultative council . In Islamic context, the Majlis-ash-Shura is one of two ways that a Khalifa (Islamic leader) may be selected, the other way being by nomination .
In the context of Islam, however, the word acquires a narrower meaning. The Muslim Khalifa is the successor (in a line of successors) to Prophet Muhammad's position as the political, military, and administrative leader of the Muslims.HILAFAH (Arabic) - is used to denote the government of the Muslim state, of which the Khalifa is the head. A workable analogy of Khalifah and Khilafah is president and presidency or king and monarchy.
