Sura al-Isrāʾ 17:79

وَمِنَ ٱلَّيْلِ فَتَهَجَّدْ بِهِۦ نَافِلَةً لَّكَ عَسَىٰٓ أَن يَبْعَثَكَ رَبُّكَ مَقَامًا مَّحْمُودًا

wa-mina l-layli fa-tahajjad bihi nāfilatan laka ʿasā an yabʿathaka rabbuka maqāman maḥmūdan

And pray in the small watches of the morning: (it would be) an additional prayer (or spiritual profit) for thee: soon will thy Lord raise thee to a Station of Praise and Glory!
