17:79 Al-Israa

وَمِنَ اللَّيْلِ فَتَهَجَّدْ بِهِ نَافِلَةً لَكَ عَسَىٰ أَنْ يَبْعَثَكَ رَبُّكَ مَقَامًا مَحْمُودًا

And from [part of] the night, pray with it as additional [worship] for you; it is expected that your Lord will resurrect you to a praised station.

17:80 Al-Israa

وَقُلْ رَبِّ أَدْخِلْنِي مُدْخَلَ صِدْقٍ وَأَخْرِجْنِي مُخْرَجَ صِدْقٍ وَاجْعَلْ لِي مِنْ لَدُنْكَ سُلْطَانًا نَصِيرًا

And say, "My Lord, cause me to enter a sound entrance and to exit a sound exit and grant me from Yourself a supporting authority."

73:2 Al-Muzzammil

قُمِ اللَّيْلَ إِلَّا قَلِيلًا

Arise [to pray] the night, except for a little -

73:3 Al-Muzzammil

نِصْفَهُ أَوِ انْقُصْ مِنْهُ قَلِيلًا

Half of it - or subtract from it a little

73:4 Al-Muzzammil

أَوْ زِدْ عَلَيْهِ وَرَتِّلِ الْقُرْآنَ تَرْتِيلًا

Or add to it, and recite the Qur'an with measured recitation.
