Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ سَأَلَ عَلِيُّ بْنُ يَقْطِينٍ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ: عَنْ رَجُلٍ دَفَعَ إِلَى خَمْسَةِ نَفَرٍ حَجَّةً وَاحِدَةً فَقَالَ «يَحُجُّ بِهَا بَعْضُهُمْ وَ كُلُّهُمْ شُرَكَاءُ فِي اَلْأَجْرِ » فَقَالَ لَهُ لِمَنِ اَلْحَجُّ، فَقَالَ «لِمَنْ صَلِيَ فِي اَلْحَرِّ وَ اَلْبَرْدِ».
Ali ibn Yaqtin asked Imam Abu Al-Hasan عليه السلام about a man who entrusted the cost of one Hajj to five people. Imam عليه السلام replied: "One of them performs the Hajj, and all of them share in the reward." Ali ibn Yaqtin then asked: "Who is the Hajj attributed to?" Imam عليه السلام replied: "It is for the one who prayed in both the heat and the cold."
