تفسير : (they glorify (him) night and day) they pray to him at night and during the day; (they flag not) they do not get bored of worshipping allah and of acknowledging his lordship.
Jalāl al-Dīn al-Maḥallī
تفسير : they glorify [him] night and day, and they do not falter, in it, for it comes to them as [naturally as] breathing comes to us, [something] which we can never be distracted from.
