Surah Ar-Ra'd 13:8
ٱللَّهُ يَعْلَمُ مَا تَحْمِلُ كُلُّ أُنثَىٰ وَمَا تَغِيضُ ٱلْأَرْحَامُ وَمَا تَزْدَادُ ۖ وَكُلُّ شَىْءٍ عِندَهُۥ بِمِقْدَارٍ ٨
EnglishSahih International
Allah knows what every female carries and what the wombs lose [prematurely] or exceed. And everything with Him is by due measure.
