He it is Who created you from a single being, and of the same (kind) did He make his mate, that he might incline to her; so when he covers her she bears a light burden, then moves about with it; but when it grows heavy, they both call upon Allah, their Lord: If Thou givest us a good one, we shall certainly be of the grateful ones.

Until when Our command came and water came forth from the valley, We said: Carry in it two of all things, a pair, and your own family-- except those against whom the word has already gone forth, and those who believe. And there believed not with him but a few.

And Allah created you of dust, then of the life-germ, then He made you pairs; and no female bears, nor does she bring forth, except with His knowledge; and no one whose life is lengthened has his life lengthened, nor is aught diminished of one's life, but it is all in a book; surely this is easy to Allah.
