4:24And all married women, except those you rightfully possess. This is God’s decree, binding upon you. Permitted for you are those that lie outside these limits, provided you seek them in legal marriage, with gifts from your property, seeking wedlock, not prostitution. If you wish to enjoy them, then give them their dowry—a legal obligation. You commit no error by agreeing to any change to the dowry. God is All-Knowing, Most Wise.

4:44Have you not considered those who were given a share of the Book? They buy error, and wish you would lose the way.

4:92Never should a believer kill another believer, unless by error. Anyone who kills a believer by error must set free a believing slave, and pay compensation to the victim’s family, unless they remit it as charity. If the victim belonged to a people who are hostile to you, but is a believer, then the compensation is to free a believing slave. If he belonged to a people with whom you have a treaty, then compensation should be handed over to his family, and a believing slave set free. Anyone who lacks the means must fast for two consecutive months, by way of repentance to God. God is All-Knowing, Most Wise.

4:102When you are among them, and you stand to lead them in prayer, let a group of them stand with you, and let them hold their weapons. Then, when they have done their prostrations, let them withdraw to the rear, and let another group, that have not prayed yet, come forward and pray with you; and let them take their precautions and their weapons. Those who disbelieve would like you to neglect your weapons and your equipment, so they can attack you in a single assault. You commit no error, if you are hampered by rain or are sick, by putting down your weapons; but take precautions. Indeed, God has prepared for the disbelievers a demeaning punishment.

4:116God will not forgive that partners be associated with Him; but will forgive anything less than that, to whomever He wills. Anyone who ascribes partners to God has strayed into far error.

4:136O you who believe! Believe in God and His messenger, and the Book He sent down to His messenger, and the Book He sent down before. Whoever rejects God, His angels, His Books, His messengers, and the Last Day, has strayed far in error.
