Points inferred from the hadith:
1 – The farewell ṭawāf is obligatory for everyone departing from Mecca, whether pilgrim or otherwise. Shaykh al-Islam Ibn Taymiyyah said: “The farewell ṭawāf is not part of the pilgrimage itself; rather, anyone who leaves Mecca must bid the House farewell. For that reason, according to the sound view, one who remains in Mecca does not perform it. Its obligation is simply to make the House the last thing a departing person attends to.”
2 – A menstruating woman is not required to perform the farewell ṭawāf, and no expiation is due for leaving it.
3 – The farewell ṭawāf should be the traveler’s final act, for that is the essence of a farewell. Minor matters that may follow it—such as buying a few provisions on the way out, waiting for travel companions, or any other brief delay of that sort—do not affect its validity.

Scholarly disagreement:
• Mālik held that the farewell ṭawāf is recommended, not obligatory for everyone, since it is waived for a menstruating woman; if it were truly obligatory, it would never be waived under any circumstance.
• The majority—including the other three Imams—maintain that it is obligatory for all except the menstruating woman, relying on the plain wording of the prophetic command. Ibn al-Munḏir said: “The great majority of the jurists of the various cities state that a menstruating woman who has already performed the ṭawāf of ifāḍa is not required to perform a farewell ṭawāf.”
