 ٤ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنْ صَفْوَانَ عَنْ مَنْصُورٍ عَنْ عَبْدِ الرَّحِيمِ الْقَصِيرِ عَنْ ابي جعفر (عَلَيْهِ السَّلام) فِي قَوْلِ الله تَبَارَكَ وَتَعَالَى إِنَّما أَنْتَ مُنْذِرٌ وَلِكُلِّ قَوْمٍ هادٍ فَقَالَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وَآلِه) الْمُنْذِرُ وَعَلِيٌّ الْهَادِي أَمَا وَالله مَا ذَهَبَتْ مِنَّا وَمَا زَالَتْ فِينَا إِلَى السَّاعَةِ.
 4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from Safwan from Mansur from ‘Abd al-Rahim al-Qusayr who has said that asked Imam abu Ja’far  about the meaning of the words of Allah, “. . For every nation there is a guide. (13:7)” The Imam  said, “The Holy Prophet (s.a.) is the Warner and Amir al-Mu’minin  is the guide. Let it be known, I swear by Allah, that guidance never departed us, it is with us and will always be with us until the Day of Judgment.”
