In Islam adultery is haram looked upon as a major sin, on the popular Islamqa.info website which is run by Muslims we read the following on the about page “Islam Q&A is an academic, educational, da‘wah website which aims to offer advice and academic answers based on evidence from religious texts in an adequate and easy-to-understand manner. These answers are supervised by Shaykh Muhammad Saalih al-Munajjid (may Allah preserve him).” A Muslima contacted Islamqa.info who suspected her husband of committing adultery she said:
According to Muslims zina (unlawful sexual relationship) is haram and needs to be repented of to Allah. Here’s the problem in the Hadith of Sahih Muslim we’re told Allah determines how much adultery a person will commit.

Now the question is how can Allah punish anyone if they are only doing the very thing Allah has commanded for that person to indulge in? On the Islamiq.info site, they said a person must: “do a lot of righteous deeds, and seek good company who will encourage him to do good and obey Allah and to avoid evil and sin.”
But the person who has committed adultery is already obeying Allah because Allah made him/her do it. This brings us to the belief of determinism in Islam, that Allah determines everything to happen. Therefore, according to the teachings of the Qur’an adultery, abortion, rape, thief and anything else comes from Allah determining it to happen.
To substantiate our claim that Islam teaches determinism, we’ll look at another Hadith, concerning an argument between Adam and Moses.

In this Sahih Hadith, we have Moses blaming Adam for them being kicked out of paradise (Jannah). Moses blames Adam but what really happened is that Allah made (determined) that Adam would commit sin by eating from the tree and thereby getting kicked out of paradise. Adam tells Moses that Allah decreed that Adam would sin 40 years before Adam was created.
If Allah made Adam eat from the tree then why is Adam being blamed for obeying Allah’s command? There you go folks, Islam the most ridiculous religion, if Allah causes people sin how can Allah be justified in punishing them for what he has decreed for them to do? This makes Allah an unjust god and is further proof that Allah is not the true God (Yahweh) of the Bible.
