الاسراۤء — Al-Isra' Ayat 79

وَمِنَ الَّيْلِ فَتَهَجَّدْ بِهٖ نَافِلَةً لَّكَۖ عَسٰٓى اَنْ يَّبْعَثَكَ رَبُّكَ مَقَامًا مَّحْمُوْدًا

Wa minal-laili fa tahajjad bihī nāfilatal lak(a), ‘asā ay yab‘aṡaka rabbuka maqāmam maḥmūdā(n).

"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."
