And after that no revelation came down to abrogate it, and the Prophet ﷺ passed away while it was still in force and never repealed. How, then, can someone rely on his own opinion and prohibit it?

He was alluding to ʿUmar ibn al-Khaṭṭāb’s—may Allah be pleased with him—discouraging tamattuʿ during the months of Ḥajj, an ijtihād on his part meant to ensure that visitors would come to the House throughout the year; for if they combined it with Ḥajj, they would not return outside the pilgrimage season.

Yet the Book of Allah and the Sunnah of His Messenger ﷺ are more deserving of obedience than anyone’s statement, whoever he may be.

Lessons drawn from the ḥadith
1 – The legitimacy of tamattuʿ and its firm establishment in both the Qur’an and the Sunnah.
2 – The Prophet ﷺ died while its ruling remained effective and un-abrogated.
3 – It is impermissible to follow an opinion that contradicts what has come from Allah or from the Messenger of Allah ﷺ.
4 – His words, “No Qur’an was revealed to forbid it,” prove that abrogation exists in the Sharia and that one Qur’anic verse may abrogate another.
5 – His words, “Nor did he forbid it,” indicate that the Qur’an may also be abrogated by the Sunnah; for had abrogation been impossible, there would have been no need to exclude the possibility that the Prophet ﷺ himself had annulled the ruling—one that is established by Qur’anic text.
6 – His words, “A man then spoke according to his own opinion as he wished,” were explained by al-Bukhārī as referring to ʿUmar ibn al-Khaṭṭāb; similar reports mention ʿUthmān and Muʿāwiyah—may Allah be pleased with them.
Their intent was simply that people should not confine their visit to the House to the season of Ḥajj alone, but should come throughout the year.

However, the Book of Allah and the Sunnah of His Messenger ﷺ take precedence over every ijtihād. Allah knows best the secrets of His law.

Now that the Muslims unanimously agree on the permissibility of tamattuʿ and routinely perform ʿumrah during the months of Ḥajj, the House is never without visitors at any time.

We ask Allah, exalted is He, to raise high His word, spread His religion, and uphold His rites. Āmīn.

Fourth ḥadith
ʿAbdullāh ibn ʿUmar—may Allah be pleased with them both—said: “During the Farewell Pilgrimage the Messenger of Allah ﷺ performed tamattuʿ, combining ʿumrah with Ḥajj, and he offered a sacrifice, driving his animals with him from Dhū’l-Ḥulayfah. The Messenger of Allah ﷺ began by entering iḥrām for ʿumrah, and then he entered iḥrām for Ḥajj.

“So the people performed tamattuʿ with the Messenger of Allah ﷺ and entered iḥrām for ʿumrah followed by Ḥajj.”
