Al Isra’ Ayah 78

أَقِمِ ٱلصَّلَوٲةَ لِدُلُوكِ ٱلشَّمْسِ إِلَىٰ غَسَقِ ٱلَّيْلِ وَقُرْءَانَ ٱلْفَجْرِ‌ۖ إِنَّ قُرْءَانَ ٱلْفَجْرِ كَانَ مَشْهُودًا ٧٨ Observe the prayer from the decline of the sun until the darkness of the night and the dawn prayer, for certainly the dawn prayer is witnessed ?by angels?.
