What is the Islamic constitution that governs people's relationships in the mosque, and is there a separation between religion and state such that a sheikh is not accepted as an imam for both religion and worldly affairs, and is it permissible for a Muslim to accept what the people of desires propose, and will he be sinful for supporting them in establishing this new tradition in mosques?

The mosque does not have a constitution in the known sense. Rather, its function is prayer, remembrance of Allah, recitation of the Quran, dissemination of knowledge, and calling to Allah. The Prophet’s Mosque, peace and blessings be upon him, was the center of da‘wah (calling to Islam), consultation, the launching point for expeditions, and the management of affairs. It is not permissible to restrict the Imam or prevent him from calling to Allah. The correct understanding is that mosques were built for the remembrance of Allah, prayer, knowledge, and discussion of good deeds. Islam does not separate religion from life; it is a religion that considers the welfare of creation and encourages knowledge and da‘wah. The imamate is an honorable position. The Imam is appointed by the Sultan or his deputy, or by those whom the people of the locality approve if no ruler exists. It is not permissible to appease people of desires in matters that contradict the Sharia.
