Qur'an 20:130

فَٱصْبِرْ عَلَىٰ مَا يَقُولُونَ وَسَبِّحْ بِحَمْدِ رَبِّكَ قَبْلَ طُلُوعِ ٱلشَّمْسِ وَقَبْلَ غُرُوبِهَا ۖ وَمِنْ ءَانَآئِ ٱلَّيْلِ فَسَبِّحْ وَأَطْرَافَ ٱلنَّهَارِ لَعَلَّكَ تَرْضَىٰ

Therefor (O Muhammad), bear with what they say, and celebrate the praise of thy Lord ere the rising of the sun and ere the going down thereof. And glorify Him some hours of the night and at the two ends of the day, that thou mayst find acceptance.
