Al-Isra 17:78
أَقِمِ ٱلصَّلَوٰةَ لِدُلُوكِ ٱلشَّمْسِ إِلَىٰ غَسَقِ ٱلَّيْلِ وَقُرْءَانَ ٱلْفَجْرِ ۖ إِنَّ قُرْءَانَ ٱلْفَجْرِ كَانَ مَشْهُودًا
Aqimi assalatalidulooki ashshamsi ila ghasaqi allayli waqur-anaalfajri inna qur-ana alfajri kana mashhooda
"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."
Al-Isra 17:78, translation by Sahih International
A short reflection
Establish prayer at the decline of the sun until the darkness of the night, and the Quran of Fajr. Indeed, the Quran of Fajr is witnessed.
