The Muslim faith allows you to LIE, CHEAT, STEAL, KILL, RAPE, and even deny Allah, over and over and over.
In the Quran, Allah, allegedly, says:
” Allah will not call you to account for what is futile in your oaths, but He will call you to account for your deliberate oaths: for expiation, feed ten indigent persons, on a scale of the average for the food of your families; or clothe them; or give a slave his freedom. If that is beyond your means, fast for three days. That is the expiation for the oaths ye have sworn. But keep to your oaths. Thus doth Allah make clear to you His signs, that ye may be grateful.” Surah 5:89
“Allah will not call you to account for thoughtlessness (vain) in your oaths, but for the intention in your hearts; and He is Oft-forgiving, Most Forbearing.” Surah 2:225
The noted Islamic commentator, Al-Tabary explained Surah 16:106 as a verse that had been revealed to Mohammed after he learned that Ammar Ibn Yasser was forced to deny his faith in Mohammed when kidnapped by the Banu Moghera tribe. Mohammed consoled Ammar by telling him, “If they turned, you turn.” (Meaning: if they again capture you, you are allowed to deny me again.)
These and similar passages from the Quran clearly reveal that Muslims’ unintentional lies are forgivable and that even their intentional lies can be absolved by performing extra duties. It is also clear that if forced to do so, Muslims can lie while under oath and can even falsely deny faith in Allah, as long as they maintain the profession of faith in their hearts.
I'm curious how you think this differs in essence from Christian doctrine and particularly the Catholic doctrine of confession and absolution.
According to Christianity, God will forgive any of our sins, even rejection of him. Peter denied Christ three times on the day He died, yet Christ forgave him. Even made him the first Pope, according to some.
