 ٧ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ عَنْ مَنْصُورِ بْنِ يُونُسَ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ قُلْتُ لابِي عَبْدِ الله (عَلَيْهِ السَّلام) رَجُلٌ قَالَ لِيَ اعْرِفِ الاخِرَ مِنَ الائِمَّةِ وَلا يَضُرُّكَ أَنْ لا تَعْرِفَ الاوَّلَ قَالَ فَقَالَ لَعَنَ الله هَذَا فَإِنِّي أُبْغِضُهُ وَلا أَعْرِفُهُ وَهَلْ عُرِفَ الاخِرُ إِلا بِالاوَّلِ.
 7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn ’Isma‘il from Mansur ibn Yunus from Muhammad ibn Muslim who has said the following. “I said to abu ‘Abdallah , “A man said to me, “You must know the last of the Imams and it does not matter if you would not know the first of the Imams.” The narrator has said that the Imam  said, “May Allah condemn this. I am angry with him and I do not know him. How can the last Imam be recognized except through the first Imam?”
