ٱللَّهُ يَعْلَمُ مَا تَحْمِلُ كُلُّ أُنثَىٰ وَمَا تَغِيضُ ٱلْأَرْحَامُ وَمَا تَزْدَادُ ۖ وَكُلُّ شَىْءٍ عِندَهُۥ بِمِقْدَارٍ

Allahu yaAAlamu ma tahmilukullu ontha wama tagheedu al-arhamuwama tazdadu wakullu shay-in AAindahu bimiqdar

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