﴿ ٱللَّهُ يَعْلَمُ مَا تَحْمِلُ كُلُّ أُنثَىٰ وَمَا تَغِيضُ ٱلْأَرْحَامُ وَمَا تَزْدَادُ ۖ وَكُلُّ شَىْءٍ عِندَهُۥ بِمِقْدَارٍ ﴾
“God knows what any female bears [in her womb], and by how much the wombs may fall short [in gestation], and by how much they may increase [the average period]: for with Him everything is [created] in accordance with its scope and purpose.”
(Allah knoweth that which every female beareth) whether it is a male or a female (and that which the wombs absorb) and the female whose pregnancy is less than nine months (and that which they grow) and the female whose pregnancy is more than nine months. (And everything) the increase, decrease, the delivery of the child and its stay in its mother's womb (with Him is measured).
