One clear example from authentic Islamic sources shows how Muhammad developed rulings based on his own observations and later claimed they came from Allah.

Sahih Muslim 1442b The Prophet stated: “I was about to forbid intimacy with women who are breastfeeding, but I looked at the Romans and Persians—they do the same with their nursing women, and it causes no harm.”

This narration is powerful proof that no all-knowing Allah exists above. Instead, Muhammad personally shaped the rules of Islam and then attributed them to revelation. For anyone willing to think critically, this single report is sufficient to undermine the foundation of the faith.

Had the Romans and Persians not followed this practice, Islamic law would have banned relations with breastfeeding women today—and Muslims would be scrambling with weak justifications for this outdated and unscientific rule, much like they do for the flawed waiting period prescribed for pregnant widows or divorcees.

Sunan Abi Dawud 2158 The Prophet declared: “It is unlawful for a believer in Allah and the Last Day to irrigate what another has already sown” (referring to intercourse with a pregnant woman).

Modern biology proves Muhammad was incorrect here. Once conception occurs from one man, subsequent relations with another have no impact on the fetus—its genetic makeup remains unchanged. These were misconceptions from pre-Islamic times that Muhammad carried forward.

His mistake again burdens women:

• A pregnant woman cannot remarry.
• Her physical and emotional needs go unmet.
• She lacks a partner’s companionship and support.
• She endures the hardships of pregnancy in isolation.

If another man offers affection, care, and joy to a pregnant woman—benefiting both her and the unborn child—what harm is there?

Why should faith demand that she suffer alone, potentially harming mother and baby?

The Concept of Grave Torment Was Also Borrowed—from a Jewish Woman

Sahih Muslim 584 Aisha narrated: The Prophet came to my home while a Jewish woman was present. She said: “Do you realize you will face trial in the grave?” Hearing this, the Messenger trembled and replied: “That applies only to the Jews.” Aisha continued: After a few nights passed, the Messenger said: “It has been revealed to me that you too will be tried in the grave.”

For those who reflect deeply, this episode reveals telling signs of the reality.

The Bigger Picture

• Muhammad initially leaned toward one ruling, then reversed it after observing non-Muslim societies.
• His view on pregnancy was scientifically wrong.
• Grave punishment: first rejected as Jewish-only, then adopted after hearing the woman—and presented as fresh revelation.

These are not commands from an omniscient deity. They are personal decisions Muhammad made, then framed as divine guidance.
