2931 - سُئِلَ أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ : عَنْ رَجُلٍ مَاتَ وَ لَهُ اِبْنٌ فَلَمْ يَدْرِ حَجَّ أَبُوهُ أَمْ لاَ قَالَ «يَحُجُّ عَنْهُ فَإِنْ كَانَ أَبُوهُ قَدْ حَجَّ كُتِبَ لِأَبِيهِ نَافِلَةٌ وَ لِلاِبْنِ فَرِيضَةٌ وَ إِنْ لَمْ يَكُنْ حَجَّ أَبُوهُ كُتِبَ لِأَبِيهِ فَرِيضَةٌ وَ لِلاِبْنِ نَافِلَةٌ ».
Hadith.2931 - Abu Abdullah 
was asked about a man who passed away and left behind a son, but it was not known whether the father had performed Hajj.
Imam said: "The son should perform Hajj on his behalf. If the father had already performed Hajj, it will be recorded as a supererogatory act (nafl) for the father and as fulfilling the obligation (faridah) for the son. If the father had not performed Hajj, it will be recorded as fulfilling the obligation for the father and as a supererogatory act for the son."
