﴿ أَقِمِ ٱلصَّلَوٰةَ لِدُلُوكِ ٱلشَّمْسِ إِلَىٰ غَسَقِ ٱلَّيْلِ وَقُرْءَانَ ٱلْفَجْرِ ۖ إِنَّ قُرْءَانَ ٱلْفَجْرِ كَانَ مَشْهُودًۭا ﴾

“BE CONSTANT in [thy] prayer from the time when the sun has passed its zenith till the darkness of night, and [be ever mindful of its] recitation at dawn: for, behold, the recitation [of prayer] at dawn is indeed witnessed [by all that is holy].”

Establish prayer from the sun’s decline that is from after midday until the dark of night until its darkness has fallen in other words perform prayers at noon in the afternoon at sunset and at night and the recital of the Qur’ān at dawn the morning prayer. Verily the dawn recital is ever witnessed it is witnessed by the angels of the night and the angels of the day.
