Paradise no relation doubt
Islam
In Islam, a believer's faith in the metaphysical aspects of Islam is called Iman (Arabic: الإيمان), which is complete submission to the will of God, not unquestionable or blind belief. A man must build his faith on well-grounded convictions beyond any reasonable doubt and above uncertainty. According to the Quran, Iman must be accompanied by righteous deeds and the two together are necessary for entry into Paradise. In the Hadith of Gabriel, Iman in addition to Islam and Ihsan form the three dimensions of the Islamic religion.
Muhammad referred to the six axioms of faith in the Hadith of Gabriel: "Iman is that you believe in God and His Angels and His Books and His Messengers and the Hereafter and the good and evil fate [ordained by your God]." The first five are mentioned together in the Qur'an The Quran states that faith can grow with remembrance of God. The Qur'an also states that nothing in this world should be dearer to a true believer than faith.
