Surah Ar-Ra'd, Verse 8

ٱللَّهُ يَعۡلَمُ مَا تَحۡمِلُ كُلُّ أُنثَىٰ وَمَا تَغِيضُ ٱلۡأَرۡحَامُ وَمَا تَزۡدَادُۚ وَكُلُّ شَيۡءٍ عِندَهُۥ بِمِقۡدَارٍ٨

al-lahu yaʿlamu mā taḥmilu kullu unthā wamā taghīḍu l-arḥāmu wamā tazdādu wakullu shayin ʿindahu bimiq'dārin

Allāh knows what every female carries and what the wombs lose [prematurely] or exceed. And everything with Him is by due measure.
