Dhikr (or Zikr, "Remembrance [of God]", "pronouncement", "invocation") Arabic: ذکر‎ ḏikr, plural أذكار ʾaḏkār; Arabic pronunciation: [ðɪkr, ʔæðˈkɑːr]), is an Islamic devotional act, typically involving the repetition - aloud or silently - of the Names of God, and of supplications taken from hadith texts and Qur'anic verses. Dhikr is usually done individually, but in some Sufi orders it is instituted as a ceremonial activity. Linguistically, it has several distinct meanings, like many Arabic words, which are common in Islamic sources. When God is the one who performs dhikr, the meaning is distinct from the remembrance humans perform.

The word dhikr is commonly translated as "remembrance" or "invocation". In reality, it has taken a wide range and various layers of meaning. For instance, while dhikr is commonly understood as the practice of remembering God, it has also been used in the Islamic sources to indicate God as the subject and the servant as the object of dhikr, and also been directly applied to the Islamic prophet, Muhammad, as embodiment of dhikr of God.
