We have made the night and the day as two signs. We blotted out the sign of night and made the sign of the day illuminating, so that you may seek the bounty of your Lord and learn to compute the seasons and the years. We have set everything forth in detail.
われは夜と昼の2つの印を設け，夜の印を暗くした。だが昼の印は明るくして，あなたがたに（働いて）主の恩恵を祈らせ，また年数を知り，（暦法を）計算させる。われは凡てのことを詳細に説き明かした。
