Hajj is the fifth among the pillars of Islam. It is an act of worship for those who can find a way to it, and all its rituals must be taken from the Prophet's Sunnah. The Tābi‘īs used to go to the Companions of the Messenger of Allah (may Allah's peace and blessings be upon him) to ask them and learn from them the Hadīths of the Messenger of Allah (may Allah's peace and blessings be upon him) and his words and deeds in the acts of worship. In this Hadīth, Anas ibn Mālik (may Allah be pleased with him) informs that he heard the Prophet (may Allah's peace and blessings be upon him) "pronouncing Talbiyah for Hajj and ‘Umrah together" in the Farewell Hajj. This indicates that the Prophet (may Allah's peace and blessings be upon him) was performing Hajj of Qirān. Then, Bakr ibn ‘Abdullāh - who narrated this Hadīth from Anas (may Allah be pleased with him) - informed that he related to ‘Abdullāh ibn ‘Umar (may Allah be pleased with him) what Anas (may Allah be pleased with him) said. Thereupon, ‘Abdullāh (may Allah be pleased with him), commenting on the statement of Anas (may Allah be pleased with him), said: "He pronounced Talbiyah for Hajj only" i.e., the Prophet (may Allah's peace and blessings be upon him) was performing Hajj of Ifrād and did not perform ‘Umrah with it. Bakr stated that he returned to Anas (may Allah be pleased with him) and told him about this statement by Ibn ‘Umar; thereupon, Anas (may Allah be pleased with him) said: "You only count us as children" i.e., you only consider us to be children who know nothing about the conditions and Sunnahs of the Prophet (may Allah's peace and blessings be upon him). He (may Allah be pleased with him) was alluding to his young age during the period in which he accompanied and served the Prophet (may Allah's peace and blessings be upon him). When the Prophet (may Allah's peace and blessings be upon him) came to Madīnah as an emigrant, Anas (may Allah be pleased with him) was aged ten at the time. Accordingly, Anas (may Allah be pleased with him) was twenty years old during the Farewell Hajj. So, Hadīths are to be accepted from him, especially after he reached the age of adolescence and maturity. So, by these words of his, Anas (may Allah be pleased with him) expressed disapproval of anyone who may think this way about him. He, therefore, said: "I heard the Messenger of Allah (may Allah's peace and blessings be upon him) saying: Labbayk ‘Umrah and Hajj." Thus, he (may Allah be pleased with him) affirmed what he narrated from the Prophet (may Allah's peace and blessings be upon him) and that he saw and heard him do that. The correct and more predominant view is that the Prophet (may Allah's peace and blessings be upon him) performed Hajj of Qirān, as stated by Anas. Whoever advocated a different view based it on what he saw the Prophet (may Allah's peace and blessings be upon him) doing or heard him saying in the assumption of Ihrām. He who heard him assuming Ihrām for Hajj thought that he performed Hajj of Ifrād; he who heard him assuming Ihrām for ‘Umrah thought that he performed Hajj of Tamattu‘; and he who heard him assuming Ihrām for Hajj and ‘Umrah together knew that he performed Hajj of Qirān, making Hajj and ‘Umrah with one Ihrām, and that ‘Umrah was incorporated into the rituals of Hajj..
