111. This is to comfort and console the Prophet (peace be upon him), as if to say: Allah does not intend to destroy them yet, for He has appointed for them a term of respite, so you should endure with patience whatever they do against you and hear their harsh talk and go on performing the obligations of your mission. For this purpose you should offer Salat in accordance with the prescribed times because it will create in you necessary forbearance and fortitude.

“Glorify Him” means: Offer your prescribed Prayers, as is clear from Ayat 132.

Incidentally in this verse (130) the times of Salat have been prescribed: (1) Fajr Prayer before sunrise. (2) Asr Prayer before sunset. (3) Isha and Tahajjud Prayers during the hours of night. Morning and Afternoon (Dhuhr) and Evening (Maghrib) Prayers at the extremes of the day. See also (E.Ns. 91 to 97 of Surah Al-Isra).
