The prophet said "Do good to and serve your mother, then your mother, then your mother, then your father, then the near relatives and then those who come after them."

Sharia law, or law that is loosely or strictly based on the Qur'an and the Hadiths, exists in many countries that have a majority Muslim population. Only some regions with sharia law apply it to judicial or criminal issues.
Confessing sins Confess to priests for absolution from sins in the name of Christ (John 20:22-23). Prayer to the Saints. The Qur'an asks them to become repentant, seek Allah’s forgiveness, and make a sincere tawba, and assures them that if they do this, Allah will forgive them, and exonerate them from their misdeeds.
Principle Adam and Eve sinned, as have all subsequent human beings because God created us with a free will to make choices. Man was unable to adhere to laws of God, so Christ came as the ultimate sacrifice to reconcile us to God. Say, "He is Allah , [who is] One, Allah , the Eternal Refuge. He neither begets nor is born, Nor is there to Him any equivalent." - Quran: Surah Al Ikhlas
Human Nature Man has inherited "original sin" from Adam. Mankind then is inherently evil and is in need of forgiveness of their sin. Human beings are not believed to be inherently sinful, but are seen as equally capable of both good and evil. Islam also teaches that faith and action go hand-in-hand.
God's role in salvation God sent His only Divine Son to save humanity from their sins. Islam teaches us that salvation is attainable through the worship of God alone. A person must believe in God and follow His commandments.
Angels Angels are God's messengers. Spirits seen as immortal and always praising God. They never disobey God except for Lucifer (Satan) and the angels who follow him (demons). Angels are created from light and remain unseen as they worship and follow God's commands.

Position of Mary The Queen of all Saints. View is similar to the Orthodox church - the title 'Mother of God' being used more commonly than Theotokos. In addition, it is claimed that at various points in history, Mary has revealed herself to the world in apparitions. Mary receives significant admiration from Muslims. She is said by the Prophet Muhammad to be the best woman God created. She is free of sin as the mother of Jesus.
