In His Noble Book, Allah The Almighty praises those who remember and mention Him and orders the believers to remember and mention Him frequently and warns them against negligence in this regard. This is because His slaves are in dire need for remembering and mentioning Him and they can never dispense with this - even for a moment. Allah The Almighty Says (what means):

• {O you who have believed, remember Allah with much remembrance.} [Quran 33:41]
• {O you who have believed, let not your wealth and your children divert you from remembrance and mention of Allah. And whoever does that - then those are the losers.}[Quran 63:9]

•  {And establish prayer for My remembrance.} [Quran 20:14]
• {Recite, [O Muhammad], what has been revealed to you of the Book and establish prayer. Indeed, prayer prohibits immorality and wrongdoing, and the remembrance and mention of Allah is greater. And Allah knows that which you do.}[Quran 29:45]

• {That they may witness benefits for themselves and mention the Name of Allah on known days over what He has provided for them of [sacrificial] animals. So eat of them and feed the miserable and poor.} [Quran 22:28]
• {There is no blame upon you for seeking bounty from your Lord [during Hajj]. But when you depart from ‘Arafaat, remember and mention Allah at al-Mash‘ar al-Haraam. And remember Him, as He has guided you, for indeed, you were before that among those astray. Then depart from the place from where [all] the people depart and ask forgiveness of Allah. Indeed, Allah is Forgiving and Merciful. And when you have completed your rites, remember Allah like your [previous] remembrance of your fathers or with [much] greater remembrance.} [Quran 2:198-200]

Tawaaf (circumambulation), Sa‘ee (walking) between the Mounts Safa and Marwah, casting the pebbles and slaughtering the sacrifices were all legislated in order to mention and remember Allah. This is supported by a Hadeeth on the authority of ‘Aa’ishah, may Allah be pleased with her, where she said that the Prophet, ,said: “Tawaaf, Sa‘ee between Safa and Marwah, and casting the pebbles were legislated only to establish the mention and remembrance of Allah.” [At-Tirmithi and others] In a Hadeeth on the authority of Nubayshah Al-Huthali, may Allah be pleased with him, he said that the Prophet, , said: “The Days of Tashreeq are days of eating, drinking, and remembering and mentioning Allah.”[Muslim]

This shows the status of remembering and mentioning Allah in Hajj and how great it is as this is the Sunnah of the Prophet, , as he combined in his Hajj the supplication of asking Allah for things with that of remembering, mentioning and praising Him. He did not stop remembering and mentioning Allah from when he left Madeenah until he returned back to it. He kept on remembering, mentioning and praising Him with the praise and glorification that is due to Him. The Prophet, , was remembering and mentioning Allah while walking, riding his camel and in whichever state he was in. This is clear for any one who reads the description of the Hajj of the Prophet, .

The greatest Thikr (remembrance and mentioning of Allah) of Hajj is the Talbiyah (Hajj related chant) as this is the slogan of Hajj. The Prophet, , said: “The best thing[s] at Hajj are Takbeer [i.e., saying, ‘Allahu Akbar] Talbiyah, and slaughtering sacrifices.”[At-Tirmithi and others]

One of the best places for the remembrance and mentioning of Allah is Mount As-Safa and Al-Marwah. Jaabir, may Allah be pleased with him, said while he was describing the Hajj of the Prophet, ,

The Prophet started with As-Safa, climbed it until he saw the Ka‘bah, then he faced the direction of the Qiblah, said: “La ilaaha illa Allah, Allahu akbar (There is no other deity except Allah, Allah is Great).” He also said: “La ilaaha illa Allah wahdahu la shareeka lah, lahu al-mulk walahu al-hamd wa huwa ‘ala kulli shay’in qadeer, la ilaaha illa Allah wahdah, anjaza wa‘dah wa nasara ‘abdah wa hazama al-ahzaab wahdah (There is no deity but Allah Alone with no partners with Him, His is the dominion and praise is due to Him. He is over all things Competent. There is no other deity except Allah Alone. He fulfilled His promise, made His slave victorious and defeated the allies alone).”[Muslim]

The Day of ‘Arafah is another one of the times and places where the remembrance and mentioning of Allah is established, especially with regards to professing the testimony of monotheism with sincerity. ‘Abdullaah ibn ‘Amr, may Allah be pleased with him, narrated that the Prophet, , said: “The best supplication is that [done] on the Day of ‘Arafah and the best of what I and the previous prophets said is: ‘La ilaaha illa Allah wahdahu la shareeka lahu lahu al-mulk walahu al-hamd wa huwa ‘ala kulli shay’in qadeer (There is no other deity except Allah. Allah is Great. His is the dominion and praise is due to Him. He is over all things Competent).’” [At-Tirmithi]

Among the places where pilgrims should observe the remembrance and mentioning of Allah is at Muzdalifah after dawn until the daylight becomes clear. Allah The Almighty Says (what means): {But when you depart from ‘Arafah, remember and mention Allah at al-Mash‘ar al-Haraam. And remember Him, as He has guided you, for indeed, you were before that among those astray.} [Quran 2:198] When he was describing the Hajj of the Prophet, , Jaabir, may Allah be pleased with him, said, “…Then the Prophet mounted [his camel] Al-Qaswaa’ until he reached Al- Mash‘ar Al-Haraam, faced the direction of the Qiblah, supplicated to Allah, and performed Takbeer [i.e., to say, ‘Allahu Akbar’] and Tahleel [i.e. to say, ‘Laa ilaaha illa Allah’). He kept standing until light emerged.”
