Chapter on Virtues of Hajj
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «مَنْ حَجَّ عَنْ إِنْسَانٍ اِشْتَرَكَا حَتَّى إِذَا قَضَى طَوَافَ اَلْفَرِيضَةِ اِنْقَطَعَتِ اَلشِّرْكَةُ فَمَا كَانَ بَعْدَ ذَلِكَ مِنْ عَمَلٍ كَانَ لِذَلِكَ اَلْحَاجِّ».
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "Whoever performs Hajj on behalf of another shares in the reward with them until the obligatory Tawaf is completed. After that, any deed performed is solely for the one performing the Hajj."
