٢ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحَسَنِ عَنْ عَلِيِّ بْنِ يُوسُفَ عَنْ أَبِي عَبْدِ الله الْمُؤْمِنِ عَنِ ابْنِ مُسْكَانَ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ قُلْتُ لَهُ الرَّجُلُ يَحُجُّ عَنْ آخَرَ مَا لَهُ مِنَ الأَجْرِ وَالثَّوَابِ قَالَ لِلَّذِي يَحُجُّ عَنْ رَجُلٍ أَجْرُ وَثَوَابُ عَشْرِ حِجَجٍ. 
2. Muhammad ibn Yahya has narrated from Muhammad ibn al-Hassan from Ali ibn Yusuf from abu ‘Abd Allah, al-Mu’min from ibn Muskan who has said the following: “I once asked abu ‘Abd Allah , about a man who performs al-Hajj for others; if he receives any reward. He (the Imam) said, ‘For the one who performs al-Hajj for another person, there, a reward for ten al-Hajj ah is for him.’”
