Surah 42. Ash-Shura, Ayah 50

The purport of this passage is a re-affirmation of the fact that whatever happens to man is an outcome of God's unfathomable will: a fact which is illustrated in the sequence by the most common, recurrent phenomenon in man's life - the unpredictability of male or female births, as well as of barrenness: and so, too, God's bestowal of worldly happiness and unhappiness cannot be measured or predicted in terms of what man may regard as his "due".

To parents themselves it is a mystery why a male or female child is given at any birth, or how the balance of the two sexes is made up in a family or in large groups of mankind, or why in some cases the womb is barren and the would be parents are denied the joys and responsibilities of parenthood. But each individual human soul is precious in the Plan of Allah, and all these variations, besides their reactions on parents and on society, have a purpose to fulfil in the large Plan of Allah.
