Qur'an, An-Nab, Surah 78:6-13
Have We not made the earth as a wide expanse,
And the mountains as pegs?
And (have We not) created you in pairs,
And made your sleep for rest,
And made the night as a covering,
And made the day as a means of subsistence?
And (have We not) built over you the seven firmaments,
And placed (therein) a Light of Splendour?
