What does a person say at the beginning of ihram if he is performing Hajj on behalf of someone else, and in all the rituals?

The questioner : He says: What does a person say at the beginning of ihram if the pilgrim is an agent for someone else, and what does he say on the Day of 'Arafah, the Day of Sacrifice, when stoning the pillars, and in other such situations there?

The Shaykh : He says, "Labbaik (I am here) on behalf of so-and-so," based on the hadith of Ibn 'Abbas (may Allah be pleased with him and his father) So you say, "Labbaik on behalf of so-and-so." If you forget his name, you say, "Labbaik on behalf of the one who gave me agency to perform Hajj on his behalf," or a similar expression. Allah the Exalted knows it, and it is not obligatory to say this during the tawaf, the sa'y, the standing, the overnight stay at Muzdalifah, or the stoning of the pillars. It is not required if you intended it from the beginning of the ihram; that is sufficient. Therefore, the correct view is that it is not a condition in the tawaf to intend it for Hajj or 'Umrah, as long as one is in a state of ihram for Hajj or 'Umrah. Because if one is in a state of ihram for Hajj, what is this tawaf for? No, if one is in a state of ihram for Hajj, what is the first tawaf? It is the tawaf al-ifadah for Hajj. If one is in a state of ihram for 'Umrah, the tawaf is for the 'Umrah. The tawaf, the sa'y, and the standing are all parts of the worship, so the initial intention is sufficient. Just as in prayer, do you intend the bowing? No, you bow considering it a part of the prayer, and the initial intention is sufficient.
