So I swear by Mawaqi (setting or the mansions, etc.) of the stars (they traverse).
Then I swear by the setting of the stars,
(56:75) No! *36 I swear by the positions of the stars '
*36) That is, "The truth is not what you seem to think it is." Here, the use of the word /a (nay) before swearing an oath by the Qur'an's being Allah's Revelation by itself shows that the oath has been sworn to refute certain objections that the disbelievers wen raising with regard to the Qur'an.
