12ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ رِفَاعَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) عَنْ رَجُلٍ نَذَرَ أَنْ يَمْشِيَ إِلَى بَيْتِ الله الْحَرَامِ أَ يُجْزِئُهُ ذَلِكَ عَنْ حَجَّةِ الإِسْلامِ قَالَ نَعَمْ قُلْتُ وَإِنْ حَجَّ عَنْ غَيْرِهِ وَلَمْ يَكُنْ لَهُ مَالٌ وَقَدْ نَذَرَ أَنْ يَحُجَّ مَاشِياً أَ يُجْزِئُ ذَلِكَ عَنْهُ قَالَ نَعَمْ.
12. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Rifa’ah who has said the following: “I once asked abu ‘ Abd Allah (a.s.), about a man who has made a vow to walk to Bayt Allah al-Haram (the Sacred House of Allah): if it is sufficient for Hajjahta al-Islam. He (the Imam) said, ‘Yes, it is sufficient.’ I then asked, ‘What happens if he performs al-Hajj for others and he does not have any assets and has vowed to perform al-Hajj on foot? Is this kind of al-Hajj sufficient? He (the Imam) said, ‘Yes, it is sufficient.’”
