5:5 Today, all good food is made lawful for you. The food of the people of the scripture is lawful for you. Also, you may marry the chaste women among the believers, as well as the chaste women among the followers of previous scripture, provided you pay them their due dowries. You shall maintain chastity, not committing adultery, nor taking secret lovers. Anyone who rejects faith, all his work will be in vain, and in the Hereafter he will be with the losers.
How do we know someone is a believer among all the religions?
Someone who believes in God alone and worships God alone.
Unity of All Submitters
2:62 Surely, those who believe, those who are Jewish, the Christians, and the converts; anyone who (1) believes in GOD, and (2) believes in the Last Day, and (3) leads a righteous life, will receive their recompense from their Lord. They have nothing to fear, nor will they grieve.
Introduction to the Quran – Rashad Khalifa:
“While every religion has been corrupted by innovations, traditions, and false, idolatrous doctrines, there may be “Submitters” within every religion. There may be Submitters who are Christian, Jewish, Muslim, Hindu, Buddhist, or anything else. These Submitters, collectively, constitute the only religion acceptable to God. As emphasized by the theme on the front page of this book, all Submitters who are devoted to God ALONE, and do not set up any idols beside God, are redeemed into God’s eternal kingdom (). A criterion of the true submitters is that they will find nothing objectionable in the Quran.”
