The correct answer is: to.
Madina is very dear to all Muslims because it is the second holiest city in Islam after Mecca. It is the city where the Prophet Muhammad lived and died, and it is the site of many important mosques and historical sites. Muslims believe that Madina is a place of peace and tranquility, and they often visit the city on pilgrimage.
The other options are incorrect because they do not accurately reflect the relationship between Madina and Muslims. Option A, “of,” is incorrect because Madina is not a possession of Muslims. Option B, “to,” is the correct answer because it indicates that Madina is dear to Muslims. Option C, “with,” is incorrect because it does not indicate a strong emotional connection. Option D, “for,” is incorrect because it indicates that Madina is a destination for Muslims, but it does not indicate that Madina is dear to them.
