عَنْهُ عَنْ مُحَمَّدِ بْنِ اَلْحُسَيْنِ عَنْ مُحَسِّنِ بْنِ أَحْمَدَ عَنْ مُحَمَّدِ بْنِ حُبَابٍ عَنْ يُونُسَ عَنْ أَبِي عَبْدِ اَللَّهِ عَ قَالَ:« إِنَّ فَاطِمَةَ عَلَيْهَا اَلسَّلاَمُ كَانَتْ تَأْتِي قُبُورَ اَلشُّهَدَاءِ فِي كُلِّ غَدَاةِ سَبْتٍ فَتَأْتِي قَبْرَ حَمْزَةَ وَ تَتَرَحَّمُ عَلَيْهِ وَ تَسْتَغْفِرُ لَهُ.
From him, from Muhammad ibn Al-Husayn, from Muhassin ibn Ahmad, from Muhammad ibn Hubab, from Yunus, from Abu Abdullah عليه السلام:
Imam عليه السلام said: "Indeed, (Sayyida) Fatimah صلى الله عليه وعلى آله وسلم, peace be upon her, used to visit the graves of the martyrs every Saturday morning. She would go to the grave of Hamzah عليه السلام, pray for mercy upon him, and seek forgiveness for him."
