This paper attempts to look at the various immoral activities available in the Nigerian society such as cultism, armed robbery, corruption, abortion, fornication, obscene dressing, theft, violence, looting, killing, and many more. These are some of dreadful acts which have deprived Nigeria of its due development.Moral decadence in the life of Nigerians appears to be spreading too fast as to be noticed in every facet of the society. This cancerous disease spreads like gangrene among Nigerians of every decade. This decadent behaviour is manifested in every sphere of life. At the rate they are presently moving, one wonders whether the future of this country would be safe. This paper therefore makes an in road into seeing the Islamic approaches to solving moral degeneration in the society. The paper finally offers some Islamic moral values system as a solution that could help promote moral standard in Muslims and Nigerians particular in all other aspects of life as a whole in Nigeria.
