Al A’raf Ayah 205

وَٱذْكُر رَّبَّكَ فِى نَفْسِكَ تَضَرُّعًا وَخِيفَةً وَدُونَ ٱلْجَهْرِ مِنَ ٱلْقَوْلِ بِٱلْغُدُوِّ وَٱلْأَصَالِ وَلَا تَكُن مِّنَ ٱلْغَـٰفِلِينَ ٢٠٥ Remember your Lord inwardly with humility and reverence and in a moderate tone of voice, both morning and evening. And do not be one of the heedless.
