If Islam is the true religion and Muslims are blessed, then why do people of other faiths enjoy the worldly benefits? They are blessed too with much more than Muslims. Kindly explain.

Allah blesses people in all societies, countries, religions, organizations, etc., all over the world. If Allah only blessed Muslims, do you think there would be any non-Muslim in the world? This life is a test of belief in Allah and obedience to His commands. It will only work, if everyone is blessed and people have to choose to believe.
