وَمِنَ اللَّيْلِ فَاسْجُدْ لَهُ وَسَبِّحْهُ لَيْلًا طَوِيلًا
[76:26]
And during part of the night adore Him, and give glory to Him (a) long (part of the) night.
And part of the night, prostrate thyself to Him; and glorify Him a long night through.
And worship Him (a portion) of the night. And glorify Him through the livelong night.
