Hadith.3129 - It is narrated from Ali ibn Yaqtin, who said
I asked Abu Al-Hasan Al-Awwal (as) about a man who finances the Hajj for five people, but only one of them actually performs it. Does everyone receive a reward?
Imam (as) said: "Yes, each one of them receives the reward of a pilgrim."
I then asked: "Which of them has the greatest reward?"
Imam (as) replied: "The one who endures the heat and the cold. If the person is performing Hajj for the first time (ṣarūr), this does not suffice on behalf of the others, and the Hajj belongs to the one who performs it."
