الاعراف — Al-A'raf Ayat 205
وَاذْكُرْ رَّبَّكَ فِيْ نَفْسِكَ تَضَرُّعًا وَّخِيْفَةً وَّدُوْنَ الْجَهْرِ مِنَ الْقَوْلِ بِالْغُدُوِّ وَالْاٰصَالِ وَلَا تَكُنْ مِّنَ الْغٰفِلِيْنَ
Ważkur rabbaka fī nafsika taḍarru‘aw wa khīfataw wa dūnal-jahri minal-qauli bil-guduwwi wal-āṣāli wa lā takum minal-gāfilīn(a).
"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."
