For example...
For example: There is a tradition that mentions the excellence of taking other believers as partners in recommended Hajj. That which proves it is are traditions that talk of doing it absolutely on behalf of all believers. After that it is derived from traditional reports that doing Hajj of proxy on behalf of the Imam of the believers is more deserving.
There is a traditional report of Muhammad bin Hasan that is mentioned in Kafi and other books that His Eminence, Imam Musa Kazim (as) said: Imam Ja’far Sadiq (as) said: If you make a thousand persons as partners in your Hajj, each will get reward of a complete Hajj without there being any decrease in your reward.[^4] In the same book, through the author’s own chain of narrators it is narrated from Muhammad bin Ismail that he said: I asked His Eminence, Imam Musa Kazim (as): How many persons can I include as partners in my Hajj?
He replied: As many as you like.[^5] It is narrated from Muawiyah bin Ammar that he asked Imam Ja’far Sadiq (as): Can I make my parents partners in my Hajj? He replied: Yes, indeed Allah, the Mighty and Sublime will make it a Hajj for you and a Hajj for each of them and as it would be a good turn on your part towards them, you will also get reward for that. I asked: Can I perform Tawaf for a man and a woman who reside in Kufa?
He replied: Yes, when you begin the Tawaf, recite as follows: O Allah, accept it from so and so, as I am doing Tawaf on his/her behalf.[^6] I say: The last hadith clearly shows that taking a partner in a an act means to take him or her right from the beginning and does not mean that after doing the thing for yourself, you make him or her share in the reward. Pay attention to this point.
For example: There is a tradition which proves sending of proxy for Imams (as) to Mecca so that he may perform the Hajj on behalf of the Holy Imam (as) and to compensate that person for this.
As it is allowed for the living Imam it must also be permitted for others as there is nothing which shows that it can only be for the living Imam.[^7] In Wasail , it is narrated from Tahdhib of Shaykh Tusi through the author’s own chain of narrators from Muhammad bin Isa Yaqteeni that he said: Imam Ali Reza (as) sent through Yunus bin Abdur Rahman some clothes, servants and money to perform Hajj and ordered me to perform the Hajj on behalf of the His Eminence.
