Islam is the greatest favor of Allah with which He has distinguished the mankind and Jinn. It is only a Deen which Allah made the last of all religions. He says: “Today, I have completed your deen for you, and perfected my favor upon you, and accepted Islam as a deen for you.” (5:3) He also said: “And whoever seeks a religion other than Islam. It will never be accepted of him, and in the Hereafter he will be one of the losers.” (3:85) Hence, It is the duty of every Muslim to value this divine favor by adhering to it. This could not be accomplished without understanding all the aspects of the religion which should be based on the Qur’an and the Sunnah.
