The following is written as a companion to Genesis 3, in regards to Adam. See the note at the end to adapt the content in this page for other uses. What to know: Islam teaches that Azzam (Adam) was a prophet. Muslims are also taught that prophets don't sin. However, Islam also confirms that Adam and Eve (Hawa) took the fruit that was forbidden to them (haram.) In light of this, Adam's actions are described as a "mistake." What to say: Talk to your friend about how they understand sin. What is sin in God's eyes? How do they define it? Be "quick to listen and slow to speak" as your friend shares.
If God leads, bring the conversation to the moment of Azzam's temptation, and the reasons for his lack of submission. Talk about what the Bible reveals of him: His lack of humility; the way he grasped for more in a way that defied God's authority; his desire to be "like God"; the way he allowed a question about God's character to undermine his willingness to obey; his lack of trust. This story allows us to see how his actions poured out of his beliefs. We continue to see the link between the heart and actions in Proverbs 4:23 and Luke 6:43-49. Tell your friend that the holy Injeel says that God cares about not only the external actions, but the source of sin as well. He wants the heart to be clean. Tell your friend that al-Masih (the Anointed One) is connected to this story in a powerful way...and to hold onto these questions and considerations as you continue forward in his Word.
Note: Your friend might say, "Prophets don't sin!" at any point in reading the Bible. In Islam, even Lot is considered a prophet...and some Islamic polemicists have made viral videos on Youtube saying that the Biblical account of Lot having an incestuous relationship to his daughters is evidence that the Bible is corrupt. In general, when you hear a friend express shock that a prophet is sinning, the concept is the same...Isn't this evidence that the Bible is corrupt and dirty? Ironically, Mohammad isn't seen as corrupt or dirty for his egregious sexual sins, all done outside of what Jesus described as God's will for sexual purity and marriage. In Islam, because "God's messenger" did these acts, they are "good." If you've never talked about the alleged corruption of the Bible before, and you feel God leading you to address it, please take this opportunity to clearly defend the Word of God as holy, unchanged, and from God - giving emphasis to the theological argument: "Is mankind stronger than God, that he's able to change His Word?" If you have already talked about the allegations of corruption, consider talking about your friend's concern differently. Share that only Jesus is given the title of one without sin. Given this...why should we be surprised (or consider it a corruption) to hear that a prophet sinned?
