Rashi on Gen 32.27
כי עלה השחר. וְצָרִיךְ אֲנִי לוֹמַר שִׁירָה בַּיּוֹם (חולין צ"א):
כי עלה השחר FOR THE DAY BREAKETH, and I have to sing God’s praise at day (Chullin 91b; Genesis Rabbah 78:1).
When we have daily rituals, it's because we're dependent on Sun's cycle, but IIRC, G-d is far beyond Sun and stars, so He should have any daily cycle for Himself, only what's related to Jewish rituals.
So why do angels and G-d have Sun-related rituals?
