Hajj is the fifth pillar of Islam. The Messenger of Allah (may Allah's peace and blessings be upon him) clarified the rituals of Hajj in his words and acts, which were reported by the noble Companions (may Allah be pleased with them) just as they had learned them from the Prophet (may Allah's peace and blessings be upon him). In this Hadīth, the great Companion, ‘Abdullah ibn ‘Umar (may Allah be pleased with him and his father), reports that during the Farewell Hajj on the 10th year of Hijrah, the Messenger of Allah (may Allah's peace and blessings be upon him) "performed Tawāf al-Ifādah on the Day of Nahr", i.e., he performed Tawāf al-Ifādah at the Sacred House, referring to the Tawāf that comes after standing at ‘Arafah and throwing pebbles at Al-Jamrah al-Kubra. It was called so because the pilgrim performs it after his Ifādah (setting forth) from Mina to Makkah. The Day of Nahr is the 10th of Dhul-Hijjah and the Day of Eid al-Ad'ha. It was called so because of Nahr (slaughtering) the Hady and Ud-hiyahs on that day. Ibn ‘Umar (may Allah be pleased with him and his father) reports that the Prophet (may Allah's peace and blessings be upon him) returned after that and prayed Zhuhr in Mina, which is a valley surrounded by mountains, located on the eastern side of Makkah on the way between Makkah and ‘Arafah Mount. Mina is known to be the place of performing the rituals of Hajj and the place where the pilgrims spend the night on the Day of Tarwiyah, the Day of Nahr, and the Days of Tashrīq, as it is the place where the Jamrahs (stoning pillars) are stoned between sunrise and sunset during those days of Hajj, and it is the place where the sacrificial animals are slaughtered. It was said: The Prophet (may Allah's peace and blessings be upon him) prayed Zhuhr in Makkah, as mentioned in Sahīh Muslim on the authority of Jābir (may Allah be pleased with him) who said: "Then, the Messenger of Allah (may Allah's peace and blessings be upon him) rode and set forth towards the House and prayed Zhuhr in Makkah." It was said: What happened is that after the Prophet (may Allah's peace and blessings be upon him) had performed Tawāf al-Ifādah, the time for Zhuhr prayer became due. So, he prayed Zhuhr in Makkah at its earliest time. Then, he returned to Mina and found the people waiting to pray with him. So, he led them in prayer once again. In this way, the Hadīths could be understood together without needing to give preponderance to some of them over the other. Nāfi‘, the freed slave of Ibn ‘Umar and the one who narrated this Hadīth from him, said that Ibn ‘Umar (may Allah be pleased with him and his father) was very keen on following the Prophet (may Allah's peace and blessings be upon him) in all his actions, whether as a traveler or a resident..
