Allāh does not do “acts of worship”, however there is an instance in the Quran in which it seems that Allāh engages in an act which He orders His Angels to perform as well as those who believe – and that is evoking prayers of peace upon Prophet Muḥammad. In reality, when Allāh engages in this act, He is sending down mercy and peace; when He orders the Angels as well as the believers to do this act, He is telling them to make prayers for peace and mercy to be showered upon the Prophet – AND to submit to him unconditionally.
