Verse 205

وَٱذْكُر رَّبَّكَ فِى نَفْسِكَ تَضَرُّعًا وَخِيفَةً وَدُونَ ٱلْجَهْرِ مِنَ ٱلْقَوْلِ بِٱلْغُدُوِّ وَٱلْـَٔاصَالِ وَلَا تَكُن مِّنَ ٱلْغَـٰفِلِينَ

You shall remember your Lord with all your soul, implore earnestly, privately and without uttering a word, day and night and do not be heedless.
