Qur'an 17:78
أَقِمِ ٱلصَّلَوٰةَ لِدُلُوكِ ٱلشَّمْسِ إِلَىٰ غَسَقِ ٱلَّيْلِ وَقُرْءَانَ ٱلْفَجْرِ ۖ إِنَّ قُرْءَانَ ٱلْفَجْرِ كَانَ مَشْهُودًا
“Establish prayer at the decline of the sun [from its meridian] until the darkness of the night and [also] the Qur’ān [i.e., recitation] of dawn. Indeed, the recitation of dawn is ever witnessed.”
