537. hadíth
وَ كَانَتْ فَاطِمَةُ عَلَيْهَا اَلسَّلاَمُ تَأْتِي قُبُورَ اَلشُّهَدَاءِ كُلَّ غَدَاةِ سَبْتٍ فَتَأْتِي قَبْرَ حَمْزَةَ فَتَتَرَحَّمُ عَلَيْهِ وَ تَسْتَغْفِرُ لَهُ.
Sayyida Fatimah Al-Zahra (s.a) used to visit the graves of the martyrs every Saturday morning, and She would come to the grave of Hamzah (a.s), show mercy upon him, and seek forgiveness for him.
