One who leaves the farewell tawaf due to crowding and illness owes a sacrificial animal

Question: My mother performed Hajj on behalf of her father. At the time of the farewell tawaf, her condition did not allow her to complete it due to the severe crowding and illness. Some people told her: “Do not perform the tawaf; just recite al-Fatihah for your father.” She did so, relying on the fatwa of this ignorant person. Is it permissible for me to perform the farewell tawaf on her behalf now, or not?

Answer: This is an invalid and erroneous fatwa. The farewell tawaf is obligatory, and al-Fatihah does not suffice in its place; rather, this is sheer ignorance. She owes a sacrificial animal for leaving the farewell tawaf, because it is obligatory. An obligatory act is expiated with a sacrificial animal if a pilgrim leaves it and is unable to perform it and then travels. He expiates it with a sacrificial animal that is slaughtered in Makkah and distributed among the poor in place of his leaving the farewell tawaf. Your tawaf on her behalf does not suffice. And success is from Allah.
