2. Abu Ali al-Ash’ariy has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya from Hariz from Muhammad ibn Muslim who has said the following: “I once asked abu Ja‘far , about a man who performs al-Hajj for others: if he is required to say any particular words. He (the Imam) said, ‘He must mention him in places designated for acts of al-Hajj.’”
