Chapter on Virtues of Hajj
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «لَوْ أَشْرَكْتَ أَلْفاً فِي حَجَّتِكَ لَكَانَ لِكُلِّ وَاحِدٍ حَجٌّ مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ حَجَّتِكَ شَيْءٌ.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "If you included a thousand people in your Hajj, each one of them would receive the reward of a complete Hajj without anything being diminished from your own Hajj."
