Hadith 20822ـ أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ حَرِيزٍ عَنْ فُضَيْلِ بْنِ يَسَارٍ قَالَ إِنَّ زِيَارَةَ قَبْرِ رَسُولِ الله (صلَّى اللهُ عَلَيْهِ وَآلِه) وَزِيَارَةَ قُبُورِ الشُّهَدَاءِ وَزِيَارَةَ قَبْرِ الْحُسَيْنِ (عَلَيْهِ السَّلاَم) تَعْدِلُ حَجَّةً مَعَ رَسُولِ الله (صلَّى اللهُ عَلَيْهِ وَآلِه).
2. Ahmad ibn Muhammad has narrated from al-Hassan ibn Ali from Hariz from Fudayl ibn Yasar who (in a Mawquf manner) has said the following: “He (the Imam) (a.s.) has said, ‘Visiting the grave of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, the graves of the martyrs and the grave of Imam al-Husayn (a.s.), is equal to performing al-Hajj along with the Messenger of Allah.”
