Clarification of the Hadith: "Expel the Mushrikin from the Arabian Peninsula"

Question:
He says: We hope for a clarification of the hadith: .

Answer:
This is an address to the rulers, stating that they must not allow the mushrikin (those who associate partners with Allah) to settle in the Arabian Peninsula. As for them coming for work, trade, business interests, or as ambassadors without settling, there is no objection to that. They came to the Messenger of Allah (peace and blessings be upon him) and entered upon him in the mosque, such as the people of Najran and others; they used to enter upon him in the mosque. He even tied up Thumamah ibn Uthaynah, who was a disbeliever, in the mosque until he embraced Islam. So their coming for important matters is not prohibited, but their settling is not permitted. However, this is within the authority of the rulers, not within the authority of every individual.
