﴿قُلْ نَزَّلَهُ رُوحُ الْقُدُسِ مِنْ رَبِّكَ بِالْحَقِّ لِيُثَبِّتَ الَّذِينَ آمَنُوا وَهُدًى وَبُشْرَىٰ لِلْمُسْلِمِينَ﴾
(102) Say, [O Muḥammad], "The Pure Spirit [i.e., Gabriel] has brought it down from your Lord in truth to make firm those who believe and as guidance and good tidings to the Muslims."
