Appears 3 times in the Quran. (Root: حسب)
  1. He causes the dawn to break; and He has made the night for rest, and the sun and the moon for reckoning; this is an arrangement of the Mighty, the Knowing.

  2. Then maybe my Lord will give me what is better than your garden, and send on it a thunderbolt from heaven so that it shall become even ground without plant,

  3. The sun and the moon follow a reckoning.
