Quran 13:8 from Surah Ar-Ra'd on Divine Marvels.
ٱللَّهُ يَعۡلَمُ مَا تَحۡمِلُ كُلُّ أُنثَىٰ وَمَا تَغِيضُ ٱلۡأَرۡحَامُ وَمَا تَزۡدَادُۚ وَكُلُّ شَيۡءٍ عِندَهُۥ بِمِقۡدَارٍ
English translation: Allah knows what carries every female and what fall short the womb and what they exceed And every thing with Him (is) in due proportion
Transliteration: al-lahu ya'lamu ma tahmilu kullu untha wama taghidu al-arhamu wama tazdadu wakullu shayin indahu bimiq'darin
