What is the best way to learn about and embrace Islam in an area where there are no Muslims or mosques?

Since the questioner has recognized that Islam is the true religion, she must hasten to embrace it and begin fulfilling its obligations. Her desire to learn about Islam is commendable. To overcome the problem of not having a righteous environment, she can utilize Islamic websites, contact Islamic organizations to obtain books, and search for nearby Islamic centers to visit. If she can move to a country with a Muslim community or an Islamic center, that would be beneficial. Even if she cannot find a single Muslim, that should not prevent her from adhering to Islam. Her connection with her Lord should remain constant; she should worship Him and supplicate to Him, and prayer to Him will compensate her for everything else. Some Companions embraced Islam and remained alone among their people until they migrated to the Prophet (peace be upon him).
