Abul-Qaasim ‘Abdullaah ibn ‘Alee said:
The lips of Abul-Hasan ad-Daawoodee would not cease from [engaging in] the remembrance of Allaah.
It was narrated that when the barber wanted to trim his moustache, he said to him:
“Stop moving your lips.”
And he responded:
“Tell time [to pause], so I can then stop [moving my lips].”
