Islam

In Islam, worship refers to ritualistic devotion as well as actions done in accordance to Islamic law which is ordained by and pleasing to God. Worship included in the Five Pillars of Islam, primarily that of salat, which is the practice of ritual prayer five times daily.

According to Muhammad Asad, on his notes in The Message of the Qur'an translation on Q51:56,

Thus, the innermost purpose of the creation of all rational beings is their cognition of the existence of Allah and, hence, their conscious willingness to conform their own existence to whatever they may perceive of His will and plan: and it is this twofold concept of cognition and willingness that gives the deepest meaning to what the Quran describes as "worship". As the next verse shows, this spiritual call does not arise from any supposed "need" on the part of the Creator, who is self-sufficient and infinite in His power, but is designed as an instrument for the inner development of the worshipper, who, by the act of his conscious self-surrender to the all-pervading Creative Will, may hope to come closer to an understanding of that Will and, thus closer to Allah Himself.

In the Muslim world, the word worship (in the literal context of worshipping) is forbidden to be used if it refers to an object or action and not exclusively to Allah.
