2. Muhammad b. Yahya has narrated from Muhammad b. al-Hassan from Ali b. Yusuf from Abi ‘Abdillah al-Mu’min from Ibn Muskan who has said the following: “I once asked Abi ‘Abdillah , about a man who performs Hajj for others; if he receives any reward. He (the Imam) said, ‘For the one who performs Hajj for another person there is a reward of ten Hajj pilgrimages for him.’”
