Ar Ra'd, 8 Ayah
13:8
ٱللَّهُ يَعۡلَمُ مَا تَحۡمِلُ كُلُّ أُنثَىٰ وَمَا تَغِيضُ ٱلۡأَرۡحَامُ وَمَا تَزۡدَادُۚ وَكُلُّ شَيۡءٍ عِندَهُۥ بِمِقۡدَارٍ ٨
Al-Lahu Ya`lamu Mā Taĥmilu Kullu 'Unthá Wa Mā Taghīđu Al-'Arĥāmu Wa Mā Tazdādu ۖ Wa Kullu Shay'in `Indahu Bimiqdārin
Allah knows what every female carries and what the wombs lose [prematurely] or exceed. And everything with Him is by due measure.
