Combining the Tawaf of Departure and the Farewell Tawaf

Question:
In a previous question, it was stated that the tawaf of departure (tawaf al-ifaḍah) suffices in place of the farewell tawaf (tawaf al-wadāʿ). However, in the answer to another question on the same topic, you stated that the farewell tawaf is a pillar (rukn) and that it should be the last act performed at the House. We ask Your Eminence to provide us with a comprehensive answer; for the pilgrim is often tied up with women and children, and it is difficult for him to reach the Haram, and he is not alone?

Answer:
The farewell tawaf, and they are pillars. The farewell tawaf is obligatory (wajib) according to the most prominent opinion among the scholars, and it is merely obligatory, not a pillar. The tawaf of visitation (tawaf al-ifaḍah) is the pillar. The tawaf of Hajj, from the persistence after descending from 'Arafah, this is called the tawaf of visitation, and it is also called the tawaf of ifaḍah. The pillar of Hajj is necessary, and it is best to perform it on the days of the festival. Then, he performs the farewell tawaf afterwards when he intends to travel, combining both matters. So if he performs the tawaf of ifaḍah, which is the pillar, and delays it until the time of departure after he has finished with the people, it suffices for him in place of the tawaf of weight (tawaf al-wazn). The greater takes the place of the lesser, because the tawaf of ifaḍah is the greater, and the tawaf of weight is the lesser, so this takes its place. This suffices because it has become his last act at the House.
