Quran 7, Al-A'raf (The Heights) ⓘ
7:205And do thou (O Muhammad) remember thy Lord within thyself humbly and with awe, below thy breath, at morn and evening. And be not thou of the neglectful.
وَاذْكُرْ رَبَّكَ فِي نَفْسِكَ تَضَرُّعًا وَخِيفَةً وَدُونَ الْجَهْرِ مِنَ الْقَوْلِ بِالْغُدُوِّ وَالْآصَالِ وَلَا تَكُنْ مِنَ الْغَافِلِينَ
