Hadith 773 4ـ وَفِي نُسْخَةِ الصَّفْوَانِيِّ أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ سَيْفٍ عَنْ أَبِي بَكْرٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلام) أَنَّ عَلِيّاً صَلَوَاتُ الله عَلَيْهِ حِينَ سَارَ إِلَى الْكُوفَةِ اسْتَوْدَعَ أُمَّ سَلَمَةَ كُتُبَهُ وَالْوَصِيَّةَ فَلَمَّا رَجَعَ الْحَسَنُ دَفَعَتْهَا إِلَيْهِ.
4. Ahmad ibn Muhammad has narrated from Ali ibn al-Hakam from Sayf from Abu Bakr from Abu ‘Abdallah (a.s.) who has said the following: “When Ali (a.s.) was about to leave for Kufa he left in ’Umm Salama’s trust his books and his will. When al-Hasan (a.s.) returned to Medina she delivered all of them to him.”
