Al-A'raf 7:205

Wathkur rabbaka fee nafsikatadarruAAan wakheefatan wadoona aljahri mina alqawli bilghuduwwiwal-asali wala takun mina alghafileen

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.

Remember your Lord in your heart with humility and awe, and without speaking loudly, in mornings and evenings, and do not be among the heedless.
