Abu al-Duha (may Allah have mercy on him) said: When the verse ﴿And your god is one God; there is no deity except Him, the Most Merciful, the Especially Merciful﴾ was revealed, the polytheists were astonished and said: "Only one deity! If he is telling the truth, then let him bring us a sign." So Allah, the Mighty and Majestic, revealed: ﴿Indeed, in the creation of the heavens and the earth, and the alternation of the night and the day... for a people who use reason﴾ up to that point.
