Names of God in Islam are names attributed to God in Islam by Muslims. These names usually denote his praise, gratitude, commendation, glorification, magnification, perfect attributes, majestic qualities, and acts of wisdom, mercy, benefit, and justice from Allah as believed by Muslims. These names are commonly called upon by Muslims during prayers, supplications and remembrance, as they hold significant spiritual and theological importance, serving as a means for Muslims to connect with God.

Dhikr is a form of Islamic worship in which phrases or prayers are repeatedly recited for the purpose of remembering God. It plays a central role in Sufism, and each Sufi order typically adopts a specific dhikr, accompanied by specific posture, breathing, and movement. In Sufism, dhikr refers to both the act of this remembrance as well as the prayers used in these acts of remembrance. Dhikr usually includes the names of God or supplication from the Quran or hadith. It may be counted with either one's fingers or prayer beads, and may be performed alone or with a collective group. A person who recites dhikr is called a dhākir.
