ٱلرُّوم : ١٧

  • فَسُبۡحَٰنَ So glory be to
  • ٱللَّهِ Allah
  • حِينَ when
  • تُمۡسُونَ you reach the evening
  • وَحِينَ and when
  • تُصۡبِحُونَ you reach the morning
So exalted is Allāh when you reach the evening and when you reach the morning.
So glory be to God - in other words, [so] glorify God, meaning: perform prayer - when you enter the [time of the] night, in which there are two prayers, the sunset one (maghrib) and the later night one ('ishaa'), and when you rise in the morning, in which there is the morning prayer (subh).
