Hajj is one of the pillars of Islam, and it is an act of worship for those who can find a way to it. Its pillars, Sunnahs, and etiquettes must be taken from the Prophet (may Allah's peace and blessings be upon him). In this Hadīth, the Tābi‘i ‘Abdur-Rahmān ibn Yazīd informs that ‘Abdullāh ibn Mas‘ūd (may Allah be pleased with him) proclaimed Talbiyah when he departed from Jam‘, which is Muzdalifah. It is the third among the sacred Mashā‘ir by which the pilgrims pass and is located between Mina and ‘Arafāt. The pilgrims stay there after leaving ‘Arafāt at the end of the ninth day of Dhul-Hijjah, and then they perform therein the Maghrib and ‘Ishā’ prayers, combined and shortened, and they collect from it the pebbles for throwing Jamarāt at Mina. The pilgrims stay there till the morning of the following day, the day of Eid al-Ad'ha, after which they head to Mina. The wording of Talbiyah - according to a Hadīth reported by Ibn ‘Umar (may Allah be pleased with him) and narrated in the Two Sahīh Collections - reads: "Labbayka allahumma labbayk, labbayka la sharīka laka labbayk, inna al-hamda wa an-ni‘mata laka wa al-mulk, la sharīka lak (Here I am at Your service, O Allah, here I am at Your service; here I am at Your service, You have no partner, here I am at Your service. Indeed, the praise, the favor, and the dominion belong to You. You have no partner)." When the people heard him proclaiming Talbiyah in this place and at this time, they expressed disapproval of his Talbiyah and thought that he was a Bedouin from the dwellers of the desert who had no understanding or knowledge about the rulings of the religion. Al-Bayhaqi narrated in Al-Kubra Collection: "They said: O Bedouin, this is not a day for Talbiyah; it is a day for Takbīr." Expressing disapproval of those who criticized his Talbiyah upon departing from Muzdalifah, ‘Abdullāh ibn Mas‘ūd (may Allah be pleased with him) said: "Have people forgotten or gone astray?!" In other words, have those people forgotten the Prophet's Sunnah in Talbiyah in a situation like this and therefore they criticized it, or they have knowingly abandoned the Sunnah?! Then, He said: "I heard the one to whom Surat al-Baqarah was revealed" - meaning the Prophet (may Allah's peace and blessings be upon him) - "say in this place: Labbayka allahumma labbayk (Here I am at Your service, O Allah, here I am at Your service)" i.e., I repeat my response to You in complying with Your command to perform Hajj, and I observe Your command time and again. He mentioned Surat al-Baqarah in particular because most of the rulings on the rituals occur therein. So, it is as if he said: This is the practice of the one to whom the rituals were revealed, from whom the Shariah was taken, and who clarified the rulings; so, adopt it. The Hadīth mentions that Talbiyah is to be proclaimed in Muzdalifah. It shows how the Companions used to teach people and remind them of the Sunnah of the Prophet (may Allah's peace and blessings be upon him)..
