Allah, exalted is He, says:

 يَـٰٓأَيُّہَا ٱلَّذِينَ ءَامَنُواْ ٱذۡكُرُواْ ٱللَّهَ ذِكۡرً۬ا كَثِيرً۬ا  وَسَبِّحُوهُ بُكۡرَةً۬ وَأَصِيلاً

"O ye who believe! Celebrate the praises of Allah, and do this often; And glorify Him morning and evening." (33:41-42)

And He, exalted is He, says:

وَٱذۡكُر رَّبَّكَ فِى نَفۡسِكَ تَضَرُّعً۬ا وَخِيفَةً۬ وَدُونَ ٱلۡجَهۡرِ مِنَ ٱلۡقَوۡلِ

بِٱلۡغُدُوِّ وَٱلۡأَصَالِ وَلَا تَكُن مِّنَ ٱلۡغَـٰفِلِينَ

And do thou (O reader!) bring thy Lord to remembrance in thy (very) soul, with humility and in reverence, without loudness in words, in the mornings and evenings; and be not thou of those who are unheedful. (7:205)

And He, exalted is He, says:

وَسَبِّحۡ بِحَمۡدِ رَبِّكَ بِٱلۡعَشِىِّ وَٱلۡإِبۡڪَـٰرِ

celebrate the Praises of thy Lord in the evening and in the morning. (40:55)

And He, exalted is He, says:

فَٱصۡبِرۡ عَلَىٰ مَا يَقُولُونَ وَسَبِّحۡ بِحَمۡدِ رَبِّكَ قَبۡلَ طُلُوعِ ٱلشَّمۡسِ وَقَبۡلَ

ٱلۡغُرُوبِ فَٱصۡبِرۡ عَلَىٰ مَا يَقُولُونَ وَسَبِّحۡ بِحَمۡدِ رَبِّكَ قَبۡلَ

طُلُوعِ ٱلشَّمۡسِ وَقَبۡلَ ٱلۡغُرُوبِ

And during part of the night, (also), celebrate His praises, and (so likewise) after the postures of adoration. (50:39)

And He, exalted is He, says:

 وَلَا تَطۡرُدِ ٱلَّذِينَ يَدۡعُونَ رَبَّهُم بِٱلۡغَدَوٰةِ وَٱلۡعَشِىِّ يُرِيدُونَ وَجۡهَهُ 

Send not away those who call on their Lord morning and evening seeking His Face. (6:52)

And He, exalted is He, says:

 فَخَرَجَ عَلَىٰ قَوۡمِهِۦ مِنَ ٱلۡمِحۡرَابِ فَأَوۡحَىٰٓ إِلَيۡہِمۡ أَن سَبِّحُواْ بُكۡرَةً۬ وَعَشِيًّ۬ا

So Zakariya came out to his people from his chamber: he told them by signs to celebrate Allah's praises in the morning and in the evening. (19:11)

And He, exalted is He, says:

وَمِنَ ٱلَّيۡلِ فَسَبِّحۡهُ وَإِدۡبَـٰرَ ٱلنُّجُومِ

And for part of the night also praise thou Him― and at the retreat of the stars! (52:49)

And He, exalted is He, says:

فَسُبۡحَـٰنَ ٱللَّهِ حِينَ تُمۡسُونَ وَحِينَ تُصۡبِحُونَ  

So (give) glory to Allah, when ye reach eventide and when ye rise in the morning; (30: 17)

وَأَقِمِ ٱلصَّلَوٰةَ طَرَفَىِ ٱلنَّہَارِ وَزُلَفً۬ا مِّنَ ٱلَّيۡلِ‌ۚ إِنَّ ٱلۡحَسَنَـٰتِ

يُذۡهِبۡنَ ٱلسَّيِّـَٔاتِ‌ۚ ذَٲلِكَ ذِكۡرَىٰ لِلذَّٲكِرِينَ

And establish regular prayers at the two ends of the day and at the approaches of the night: for those things that are good remove those that are evil: be that the word of remembrance to those who remember (their Lord): (11:114)
