59. Allah's Scientific Miracles In The Quran: The Menstrual Period

The menstrual period is a recurring event in women where an unfertilised egg is expelled from the body due to the contraction of the womb, and the body begins preparations for it to occur again. Allah knows the exact measure of the shrinking and swelling of the walls of the womb during this period, which can only be identified through medical examination. The mucous on the walls of the womb is 0.5 mm thick at the beginning and grows to a thickness of 5-6 mm before being discarded. All of these stages are mentioned in the Qur'an.
