﴿ وَمِنَ ٱلَّيْلِ فَسَبِّحْهُ وَإِدْبَٰرَ ٱلنُّجُومِ ﴾

“and extol His glory at night, and at the time when the stars retreat.”

(And in the night time) upon the advent of the night (also hymn His praise) pray for Him the prayer of Zuhr, 'Asr, Maghrib and 'Isha', (and at the setting of the stars) two units of prayers after Fajr, and the setting of the star when it goes down'.
