3ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ حَمَّادٍ عَنْ عَمْرِو بْنِ يَزِيدَ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) إِنِّي سَمِعْتُكَ وَأَنْتَ تَقُولُ كُلُّ شِيعَتِنَا فِي الْجَنَّةِ عَلَى مَا كَانَ فِيهِمْ قَالَ صَدَقْتُكَ كُلُّهُمْ وَالله فِي الْجَنَّةِ قَالَ قُلْتُ جُعِلْتُ فِدَاكَ إِنَّ الذُّنُوبَ كَثِيرَةٌ كِبَارٌ فَقَالَ أَمَّا فِي الْقِيَامَةِ فَكُلُّكُمْ فِي الْجَنَّةِ بِشَفَاعَةِ النَّبِيِّ الْمُطَاعِ أَوْ وَصِيِّ النَّبِيِّ وَلَكِنِّي وَالله أَتَخَوَّفُ عَلَيْكُمْ فِي الْبَرْزَخِ قُلْتُ وَمَا الْبَرْزَخُ قَالَ الْقَبْرُ مُنْذُ حِينِ مَوْتِهِ إِلَى يَوْمِ الْقِيَامَةِ.

3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Ahmad ibn Muhammad from ‘Abd al-Rahman ibn Hammad from ‘Amr ibn Yazid who has said the following: “I said to abu ‘Abd Allah, ‘Alayhi al-Salam, ‘I have heard you say, “All of our Shi‘ah will be in paradise just as they are.’” He said, ‘I have told you the truth. All of them, by Allah, will be in paradise.’ The narrator has said that I then said, ‘May Allah keep my soul in your service, the sins are many and the major ones.’ He said, ‘On the Day of Judgment, all of you will be in paradise through the intercession of the Holy Prophet, which is obeyed or through the intercession of an executor of the will of the Holy Prophet. However I am afraid for you in Barzakh.’ I then asked, ‘What is Barzakh?’ He replied, ‘It is the grave from his death to the Day of Judgment.’”
