Mention of Dhikr in the Qur’an
Dhikr is mentioned in many places in the Qur’an, and in most verses, what was meant by the word dhikr is tasbih, glorifying; takbir, exalting; tahmid, praising; and praising and praying upon the Prophet (p).
Allah said in Surat al-Baqara, 152: “Remember Me and I will remember you.” [2:152]
He said in Surat ali cImran, 41, “…and remember your Lord much and glorify Him in the evening and in the early morning.” And again, 191, “Those who remember Allah while standing, sitting, and lying on their sides…” [3:41, 191]
He said in Surat al-Racd, 28, “Those who believe, and whose hearts find their rest in the remembrance of Allah–for, verily, in the remembrance of Allah hearts do find their rest.” [13:28]
And He said in Surat al-Ah zab, 35, “…and men who remember Allah much and women who remember Him…” And again, 41,42, “O you who believe! Remember Allah with much remembrance; and glorify Him morning and evening.” [33: 35, 41-42]
There are many, many other verses of Qur’an mentioning dhikr. Imam Nawawi said in his book, “Futahat ar-Rabbani cala-l- Adhkar an-Nawawiyya,” vol. 1, p. 106-109, “All scholars of Islam have agreed on the acceptance and permissibility of Dhikr by heart and by tongue, for the adult men and women, for children, for the one who has ablution, and for the one without ablution; even for the woman during her menses. Moreover, dhikr is allowed by all scholars in the form of tasbih, tahmid, takbir and praising and praying for the Prophet (p).”
Dhikr polishes the heart and is the source of the Divine breath that revives the dead spirits by filling them with the Blessings of Allah, decorating them with His Attributess, and bringing them from a state of heedlessness to the state of complete wakefulness. If we keep busy with Dhikrullah, happiness and peace will be granted to us. Dhikr is the key to happiness, the key to joy, and the key to Divine Love.
Mention of Dhikr in the Sunnah
According to Bukhari, Abu Musa al-Ashcari related that the Prophet (p) said, “The difference between the one who makes dhikr and the one who doesn’t make dhikr is like the difference between the living and the dead.”
Tirmidhi narrated from Anas (r) that the Prophet (p) said, “If you pass by the Paradises of Heavens stay there.” They asked, “Ya Rasul-Allah, what are the Paradises of Heavens?” He said, “The associations of Dhikr!”
Bukhari narrated in his book from Abu Huraira that the Prophet (p) said, “Allah, Almighty and Exalted, has angels who seek the people of Dhikr. If they find the people of Dhikr they encompass them until they reach the first heaven. And Allah asks his angels, ‘What are my servants doing?’ The angels say, ‘O Allah, they are praising You and glorifying You and they are making Dhikr.’ Allah says, ‘Did they see Me?’ The angels answer, ‘No, they didn’t see You.’ Then Allah asks, ‘How would it be if they were to see Me?’ The angels reply, ‘O Allah, if they were to see You, they would be making more praise of You and more glorification of You and more Dhikr of You.’ And Allah asks ‘What are they asking for?’ The angels say, ‘They are asking for Your Paradise.’ Allah asks, ‘Did they see My Paradise?’ The angels answer, ‘No, Our Lord.’ Allah continues, ‘How would it be if they saw My Paradise?’ The angels reply, ‘They would be more attracted and more eager to reach it.’ Then Allah asks them, ‘Of what are they afraid?’ And the angels say, ‘They are afraid of hellfire.’ and Allah asks, ‘How would it be if they saw my Hellfire?’ and they reply, ‘They would be running more and more away from it and asking more and more protection from it.’ Then Allah said,’ I am making you all My witnesses: that I am forgiving them of all their sins.’ Then one angel asked, ‘O our Lord, there is among these people one who is not from them, he came only to ask for something from one of them.’ Allah said, ‘Those are my beloved ones who are making My Dhikr. Anyone who comes into their circle will be forgiven, and I am forgiving him.'”
In Bukhari and Muslim it is narrated from Abu Huraira that the Prophet (p) said, “As my servant thinks about Me so will I be for him. I am with him if he will remember Me. If he calls on Me in himself I will call him in Myself, and if he calls on Me in a group of people, I mention him in a better group in My presence. If he approaches Me one handspan, I will approach him one arm’s length; if he approaches Me one arm’s length, I will approach him by a cubit; if he comes to Me walking, I will come to him running.”
Tirmidhi and Ibn Majah narrated on the authority of Abi Darda that the Prophet (p) said, “Do you want me to tell you of your best deeds, and the most honored and praised and sanctified to Your Lord, and the highest in its reward; better than spending gold and better than meeting your enemy and cutting their necks in the jihad?” They said, “Yes, Ya Rasulallah.” He said, “Dhikrullah.”
The Prophet (p) said, “Everything has its polish and the polish of hearts is dhikrullah.”
Mu’adh bin Jabal (r) said, “Nothing saves you from Allah’s punishment except Dhikrullah.”
There are many, many other hadith about the benefits and blessings of Dhikr.
