Al-Kāfi - The Book of Haj

Chapter: What Suffices for Hajjata al-Islam and What Does Not Suffice? (The following Chapter is best explained by fatwa).

ِنْ أَصْحَابِنَا عَنْ أَحْ٠َّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنْ فَضَالَةَ عَنْ رِفَاعَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَ٠ْ يَحُجَّ حَجَّةَ الإِسْلا٠ْ يُوصِ بِهَا أَ يُقْضَى عَنْهُ قَالَ نَعَ٠15.

A number of our people have narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from Fadalah from Rifa’ah who has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man who dies and has not performed Hajjahta al-Islam and has not made any will about it if it can be carried out on his behalf. He (the Imam) said, ‘Yes, it is permissible.’” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (17/166))
