In Jāhiliyyah, the Arabs used to regard assuming Ihrām for ‘Umrah during the months of Hajj (Rajab, Dhul-Qi‘dah, Dhul-Hijjah, and Muharram) as one of the worst immoral acts and gravest sins. They would prohibit ‘Umrah until the end of the month of Muharram. So, the Prophet (may Allah's peace and blessings be upon him) abolished the habits of Jāhiliyyah, including the prohibition of ‘Umrah during the months of Hajj, and established the Shariah of Islam. In this tradition, Ghunaym ibn Qays says that he asked the Companion Sa‘d ibn Abi Waqqās (may Allah be pleased with him) about Tamattu‘ in Hajj. Tamattu‘ in Hajj is when a pilgrim intends to perform ‘Umrah along with Hajj. As he comes to Makkah and performs ‘Umrah, he ends his Ihrām and enjoys all that is lawful until the beginning of the rituals of Hajj on the 8th day of Dhul-Hijjah. In response, Sa‘d (may Allah be pleased with him) said: "We performed that," i.e., we, the Companions of Muhammad (may Allah's peace and blessings be upon him), engaged in Tamattu‘, performing ‘Umrah during the months of Hajj. "When this", referring to Mu‘āwiyah ibn Abi Sufyān (may Allah be pleased with him). Perhaps he wanted to forbid Tamattu‘ altogether during the months of Hajj, and he was then the caliph of Muslims. "Was then a disbeliever," i.e., Mu‘āwiyah was following the religion of Jāhiliyyah and residing "in the shady dwellings," i.e., the houses of Makkah. This is because these houses were covered with fronds of date palms. Accordingly, the Tamattu‘ here in the words of Sa‘d (may Allah be pleased with him) is intended to refer to the ‘Umrah performed during the 7th Hijri year, which was offered to make up for an earlier missed ‘Umrah. Mu‘āwiyah was a disbeliever at the time. He embraced Islam thereafter, during the year of the Conquest of Makkah, in 8 A.H. The bottom line is that ‘Umrah was performed during the months of Hajj..
