Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ سُئِلَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلرَّجُلِ يَحُجُّ عَنْ آخَرَ أَ لَهُ مِنَ اَلْأَجْرِ وَ اَلثَّوَابِ شَيْءٌ فَقَالَ «لِلَّذِي يَحُجُّ عَنِ اَلرَّجُلِ أَجْرٌ وَ ثَوَابُ عَشْرِ حِجَجٍ وَ يُغْفَرُ لَهُ وَ لِأَبِيهِ وَ لِأُمِّهِ وَ لاِبْنِهِ وَ لاِبْنَتِهِ وَ لِأَخِيهِ وَ لِأُخْتِهِ وَ لِعَمِّهِ وَ لِعَمَّتِهِ وَ لِخَالِهِ وَ لِخَالَتِهِ إِنَّ اَللَّهَ وَاسِعٌ كَرِيمٌ».
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام was asked about a man who performs Hajj on behalf of another. "Will he receive any reward or recompense?" The Imam عليه السلام replied: "The one who performs Hajj on behalf of another receives the reward and recompense of ten Hajj. He is forgiven, along with his father, his mother, his son, his daughter, his brother, his sister, his paternal uncle, his paternal aunt, his maternal uncle, and his maternal aunt. Indeed, Allah سبحانه وتعالى is all-encompassing and generous."
