If there were only some Quran by which the mountains would travel away or the earth would crack open, or the dead would speak out! Rather command is wholly Allah (God)'s. Do not those who believe despair, because Allah (God) might have guided all mankind had He so wished? Disaster will continually afflict those who disbelieve because of what they produce, or it will settle down close to their home until Allah (God)'s promise comes true. Allah (God) does not break any promise.
— Muhammad Hijab
