It is He Who created you from a single person, and made his mate of like nature, in order that he might dwell with her (in love). When they are united, she bears a light burden and carries it about (unnoticed). When she grows heavy, they both pray to God their Lord, (saying): "If Thou givest us a goodly child, we vow we shall (ever) be grateful." (7:189)

God doth know what every female (womb) doth bear, by how much the wombs fall short (of their time or number) or do exceed. Every single thing is before His sight, in (due) proportion. (13:8)

Verily the knowledge of the Hour is with God (alone). It is He Who sends down rain, and He Who knows what is in the wombs. Nor does any one know what it is that he will earn on the morrow: Nor does any one know in what land he is to die. Verily with God is full knowledge and He is acquainted (with all things). (31:34)

And made his progeny from a quintessence of the nature of a fluid despised: (32:8)

He created you (all) from a single person: then created, of like nature, his mate; and he sent down for you eight head of cattle in pairs: He makes you, in the wombs of your mothers, in stages, one after another, in three veils of darkness. such is God, your Lord and Cherisher: to Him belongs (all) dominion. There is no god but He: then how are ye turned away (from your true Centre)? (39:6)

To Him is referred the Knowledge of the Hour (of Judgment: He knows all): No date-fruit comes out of its sheath, nor does a female conceive (within her womb) nor bring forth the Day that (God) will propound to them the (question), "Where are the partners (ye attributed to Me?" They will say, "We do assure thee not one of us can bear witness!" (41:47)

Those who avoid great sins and shameful deeds, only (falling into) small faults,- verily thy Lord is ample in forgiveness. He knows you well when He brings you out of the earth, And when ye are hidden in your mothers' wombs. Therefore justify not yourselves: He knows best who it is that guards against evil. (53:32)
