Surah Al-Muzzammil — Ayah 7

إِنَّا سَنُلْقِى عَلَيْكَ قَوْلًا ثَقِيلًا

Indeed, We will cast upon you a heavy word.

إِنَّ نَاشِئَةَ ٱلَّيْلِ هِىَ أَشَدُّ وَطْـًٔا وَأَقْوَمُ قِيلًا

Indeed, the hours of the night are more effective for concurrence [of heart and tongue] and more suitable for words.

وَٱذْكُرِ ٱسْمَ رَبِّكَ وَتَبَتَّلْ إِلَيْهِ تَبْتِيلًا

And remember the name of your Lord and devote yourself to Him with [complete] devotion.

رَّبُّ ٱلْمَشْرِقِ وَٱلْمَغْرِبِ لَآ إِلَـٰهَ إِلَّا هُوَ فَٱتَّخِذْهُ وَكِيلًا

[He is] the Lord of the East and the West; there is no deity except Him, so take Him as Disposer of [your] affairs.
