What is the ruling on establishing Friday prayer in a newly built mosque, given the presence of a nearby Sufi zawiya that later began establishing the five daily prayers and Friday prayer? And is Friday prayer valid in that zawiya?

The fundamental principle is that the people of a neighborhood should perform Friday and congregational prayers in the mosque designated for that purpose. The aforementioned zawiya (Sufi lodge) was established after the mosque and has caused disunity among Muslims, which necessitates observing the following steps:

1. Sitting down with those in charge of the zawiya and informing them that the mosque is the original place for prayer, and that there is no need to divide Muslims. 2. Dealing with the problem gently and wisely, and choosing the appropriate individuals for dialogue. 3. Kindly and wisely clarifying the deviation of these individuals and their role in causing disunity, and conveying the words of knowledgeable scholars known for their righteousness in explaining their errors, while also noting that many who affiliate themselves with righteous imams have deviated from their path.
