Qur'an 7:205 · Al-A'raaf

وَٱذْكُر رَّبَّكَ فِى نَفْسِكَ تَضَرُّعًۭا وَخِيفَةًۭ وَدُونَ ٱلْجَهْرِ مِنَ ٱلْقَوْلِ بِٱلْغُدُوِّ وَٱلْءَاصَالِ وَلَا تَكُن مِّنَ ٱلْغَٰفِلِينَ

(205) And remember your Lord within yourself in humility and in fear without being apparent in speech - in the mornings and the evenings. And do not be among the heedless.
