"It is He Who made the sun to be a shining glory and the moon to be a light of beauty, and measured out stages for her, that you might know the number of years and the count of time. Allah created this only in truth and righteousness. Thus He explains His Signs in detail, for those who understand. Truly, in the alternation of the night and the day, and in all that Allah has created, in the heavens and the earth, are signs for those who fear Him." 10:5-6
