1. Scientific Demystification:
The verse cites rain and the contents of the womb as exclusive divine secrets. Today, meteorology and ultrasound/DNA testing routinely predict rain and identify a fetus's sex, genetics, and health, dismantling the claim of exclusive knowledge.
2. Moving the Goalposts:
Faced with this, apologists claim the verse refers to the "soul" or "destiny." However, early Hadiths (e.g., Bukhari) explicitly define this as knowing the biological sex, exposing a clear theological retreat.
The Quran Verse
Surah 31:34
Indeed, Allah has knowledge of the Hour and sends down the rain and knows what is in the wombs...
The Refuted Challenge:
In the 7th century, predicting the rain or knowing the sex of a child before birth was considered "unseen" (Ghaib) and a proof of God’s exclusive knowledge.
Meteorology:
Today, satellite technology allows meteorologists to predict with high accuracy when and where it will rain.
Sonography/DNA:
Ultrasound and non-invasive prenatal testing (NIPT) allow humans to know "what is in the wombs" (including biological sex, health status, and genetic traits) very early in pregnancy.
If these five things are the "exclusive keys" of God’s knowledge, the fact that humans now possess this knowledge undermines the verse's theological weight. Apologists often move the goalposts to say God knows the "soul" or "destiny," but the plain Arabic text refers to the physical rain and the physical contents of the womb.
