Is he who denies Islamic morals and says that the morals of the general populace – which contradict what has been agreed upon by scholars and sound human nature – are the ones to be considered, and that morals change with the changing times, considered a disbeliever for denying a fundamental principle of Islam, by analogy with declaring one who denies prayer, zakat, and fasting a disbeliever, taking into account his (peace be upon him) saying: "I was only sent to perfect noble morals"?

In Islam, ethics hold a high status. The Prophet, peace and blessings be upon him, was sent to perfect noble character. It is not permissible to deny the ethics enjoined by the Sharia. Some Islamic ethics are obligatory, such as truthfulness, trustworthiness, honoring one's parents, and maintaining kinship ties. One who denies them risks disbelief. It is possible that the speaker intends the difference in customs between countries, and there is no harm in acting upon them as long as they do not contravene the Sharia.
