Some examples
Dear Muslim, I do not post these questions as a "proof" that Islam is false. I do not believe that is possible with a simple list of questions. Nevertheless, they are here to encourage discussion that the truth may be known.
The Qur'an says "To those who believe and do deeds of righteousness hath Allah promised forgiveness and a great reward" (Surah 5:9).
Question: Are you doing enough good deeds to receive salvation on the Day of Judgment?
Question: Are you doing all you can or are you relaxing in your dedication to Allah?
The Qur'an says, "O ye who believe! Turn unto Allah in sincere repentance! It may be that your Lord will remit from you your evil deeds and bring you into Gardens underneath which rivers flow, on the day when Allah will not abase the Prophet and those who believe with him. Their light will run before them and on their right hands; they will say: Our Lord! Perfect our light for us, and forgive us! Lo! Thou art Able to do all things," (66:8-9). Notice how it says if you are sincere you may receive forgiveness.
Question: How do you know you are sincere enough to be forgiven of Allah?
Question: Does it give you peace to know that even if you are very sincere that at best, you may receive forgiveness?
Question: If you say that you know you are sincere enough in your repentance before Allah, how do you know you are not deceiving yourself?
Question: Is your heart really good enough to muster enough sincerity before a Holy and Righteous God?
Question: If you say yes, I honestly and humbly ask you, "Are you being prideful?"
Question: If you say you are not being prideful, then are you boasting in your sincerity?
In Christianity, Jesus is God in flesh who paid for our sins on the cross (1 Pet. 2:24). Because of that, we Christians are secure in Him and do not have to worry (…) about doing enough good works to please God since we are saved by grace through faith in Him (add: of course good works are a tangible sign of God’s Love), (Eph. 2:8-9).
Question: Why should we Christians give up our guarantee of salvation in Jesus for the requirements of your Qur'anic law when you yourselves don't even know if you have done enough good deeds to be saved on the Day of Judgment?
The Bible says that God is love (1 John 4:16) and that He loves all people (Matt. 5:43-48; John 3:16). The Qur'an never says that "God is love." In fact, the Qur'an says that Allah does not love unbelievers (2:98; 3:32).
Question: If Allah does not love unbelievers, can you say that Allah is love, especially if the Qur'an does not say it?
Question: If you say yes, that Allah is love, then why does he only love the Muslims and not all people?
Question: If you say Allah is love, is he more loving than the God of the Bible who loves all people?
In the Bible, Jesus said in John 15:13, "Greater love hath no man than this, that a man lay down his life for his friends." In Christianity, the greatest act of love is performed by God Himself -- since Jesus is God in flesh (John 1:1, 14; Col. 2:9). Jesus is the one who fulfilled His own words on this. He laid His life down for us.
Question: What is the greatest act of love performed by Allah?
Question: If what Jesus said is true, then hasn't someone besides Allah has performed the greatest act of love?
Question: Why do you, as a Muslim, want me to give up such a great love performed by God Himself (from a Christian perspective) for your belief in Allah who only loves people if they are Muslims?
Islam teaches that the Holy Spirit is Gabriel. In the Bible, the Holy Spirit lives in the Christians.
Question: If the angel Gabriel is the Holy Spirit, how can he dwell in us?
(Note: According to the Nestle Aland Greek New Testament Textual Apparatus, there are no textual variations any of the following biblical references. They are recorded and transmitted to us accurately.)
"Guard, through the Holy Spirit who dwells in us, the treasure which has been entrusted to you," (2 Tim. 1:14, NASB).
"Do you not know that you are a temple of God, and that the Spirit of God dwells in you?" (1 Cor. 3:16, NASB).
The Qur'an states that you shall marry only up to four women: "If ye fear that ye shall not be able to deal justly with orphans, marry women of your choice, two, or threee, or four; but if ye fear that ye shall not be able to deal justly (with them), then only one, or that which your right hands possess..." (4:3).
If the Qur'an is eternal, having been written on the table in heaven, then the four wife limit was an eternal decree.
Question: Why did Muhammad have 12 wives if the Qur'an says to have only four? Khadija, Sawda, Aesah (6 years old), Omm Salama, Hafsa, Zaynab (originally the wife of Muhammad's adopted son), Jowayriya, Omm Habiba, Safiya, Maymuna, Fatima, Hend, Asma (of Saba), Zaynab, Habla, Asma?
The Qur'an says that Allah created the heavens and earth in six days. "Your Guardian Lord is Allah, who created the heavens and the earth in six days..." (7:54) See also, 10:3. 41:9 - "Say: Is it that ye deny him who created the earth in two days..."
Question: Which should we believe, the Bible or the Qur'an (…)? The Bible says God created the earth in one day, the xth day (xxx).
41:10 - "He set on the (earth), mountains standing firm, high above it, and bestowed blessings on the earth, and measured therein its sustenance in four days..."
Question: Does 41:10 included the 2 days of 41:9 above? If so, why does 41:9 say God created the earth in two days, but 41:10 says that God measured its sustenance in four days? They are different occurrences.
41:11 - "Then he turned to the sky, and it had been (as) smoke: he said to it and to the earth: 'Come ye together, willingly or unwillingly..."
41:12 - "So he completed them as seven firmaments in two days, and he assigned to heaven its duty and command..."
Question: the two days of 41:9 plus the four days of 41:10 and the 2 days of 41:12 equals eight days of creation, not six. Why is that?
It is a commonly held belief among Muslims that Muhammad was sinless.
If Muhammad was sinless, then why does the Qur'an state: "Patiently, then, persevere: for the promise of Allah is true: and ask forgiveness for thy fault, and celebrate the praises of they Lord in the evening and the morning." (40:55).
Pickthall translates 40:55 thus: "Then have patience (O Muhammad). Lo! the promise of Allah is true. And ask forgiveness of thy sin, and hymn the praise of thy Lord at fall of night and in the early hours."
The Hadith says, Narrated Abu Huraira: "I heard Allah's Apostle saying." By Allah! I ask for forgiveness from Allah and turn to Him in repentance more than seventy times a day." Volume 8, Book 75, Number 319,
Question: If it is the common belief that Muhammad was sinless, why do the Qur'an and Hadith contradict that notion? Which is correct?
The Qur'an says to have no divisions within Islam. "The same religion has He established for you as that which He enjoined on Noah - the [sic] which we have sent by inspiration to thee - and that which we enjoined on Abraham, Moses, and Jesus: namely, that ye should remain steadfast in religion and make no divisions therein: to those who worship other things than Allah, hard is the (way) to which thou callest them..." (42:13).
Question: If Islam is the truth, which of the divisions within it is the "most" true?
Question: Is Islam in a state of sin since there are divisions within its ranks?
The Qur'an says, "And dispute ye not with the People of the Book [Jews and Christians and the Bible], except in the best way, unless it be with those of them who do wrong but say, "We believe in the revelation which has come down to us and in that which came down to you," (29:46).
Question: Isn't the Qur'an here saying that the Muslim is to believe what the Bible says?
