17:79
وَمِنَ ٱلَّيْلِ فَتَهَجَّدْ بِهِۦ نَافِلَةً لَّكَ عَسَىٰٓ أَن يَبْعَثَكَ رَبُّكَ مَقَامًا مَّحْمُودًا
wamina al-layli fatahajjad bihi nāfilatan laka ʿasā an yabʿathaka rabbuka maqāman maḥmūdan
and dur-ing the night wake up and pray, as an extra offering of your own, so that your Lord may raise you to a [highly] praised status.
And in some parts of the night (also) offer the Salât (prayer) with it (i.e. recite the Qur’ân in the prayer), as an additional prayer (Tahajjud optional prayer - Nawâfil) for you (O Muhammad صلى الله عليه و سلم). It may be that your Lord will raise you to Maqâm Mahmûd (a station of praise and glory, i.e. the honour of intercession on the Day of Resurrection.).
