Sura 50 The letter Qaaf (Qaf), ayah 39

1. فَاصْبِرْ عَلَىٰ مَا يَقُولُونَ وَسَبِّحْ بِحَمْدِ رَبِّكَ قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ الْغُرُوبِ

   So be patient, (O Muhammad), over what they say and exalt (Allah) with praise of your Lord before the rising of the sun and before its setting,

   50:39
