Dhikr (also Zikr, Zekr, Zikir, Jikir, and variants; Arabic: ذِكْر‎, ) : primarily in Sufi Islam,in which short phrases or prayers are repeatedly recited silently within the mind or aloud. It can be counted on a set of prayer beads (Misbaha مِسْبَحَة) or through fingers of the hand. A person who recites the Dhikr is called a ḏākir ([ˈðaːkɪr] ذاكر). Tasbih (تسبيح) is a form of dhikr that involves the repetitive utterances of short sentences glorifying God. The content of the prayers includes the names of God, or a duʿāʾ (prayer of supplication) taken from the hadith or the Quran.

There are several verses in the Quran that emphasize the importance of remembering the will of God by saying phrases such as "God willing," "God knows best," and "If it is your will.' This is the basis for dhikr. Sura 18 (Al-Kahf), ayah 24 states a person who forgets to say, "God Willing," should immediately remember God by saying, "May my Lord guide me to do better next time."Other verses include sura 33 (Al-Ahzab), ayah 41, "O ye who believe! Celebrate the praises of Allah, and do this often,"and sura 13 (Ar-Ra'd), ayah 28, "They are the ones whose hearts rejoice in remembering God. Absolutely, by remembering God, the hearts rejoice."[5] Muhammad said, 'The best [dhikr] is La ilaha illa’llah ("there is no God but God"), and the best supplicatory prayer is Al-hamdu li’llah ("praise be to God").
Muslims believe dhikr is one of the best ways to enter the higher level of Heaven and to glorify the Oneness of Allah.[
- To Sufis, dhikr is seen as a way to gain spiritual enlightenment and achieve union (visal) or annihilation (fana) in God. All Muslim sects endorse individual rosaries as a method of meditation, the goal of which is to obtain a feeling of peace, separation from worldly values (dunya), and, in general, strengthen Iman (faith).

Allāh- الله is the Arabic word for God and mentioned in Quran most of the verses.
