Surah 54. Al-Qamar, Ayah 49

Allah's Creation is not haphazard. Everything goes by law, proportion, and measure. Everything has its appointed time, place, and occasion, as also its definite limitation. Nothing happens but according to His Plan, and every deed, word, and thought of man has its fullest consequences, except in so far as the Grace or Mercy of Allah intervenes, and that is according to law and plan.
