عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ بَعْضِ أَصْحَابِنَا عَنْ مُحَمَّدِ بْنِ الْهَيْثَمِ عَنْ زَيْدٍ أَبِي الْحَسَنِ قَالَ سَمِعْتُ أَبَا عَبْدِ اللَّهِ (عليه السلام) يَقُولُ مَنْ كَانَتْ لَهُ حَقِيقَةٌ ثَابِتَةٌ لَمْ يَقُمْ عَلَى شُبْهَةٍ هَامِدَةٍ حَتَّى يَعْلَمَ مُنْتَهَى الْغَايَةِ وَ يَطْلُبَ الْحَادِثَ مِنَ النَّاطِقِ عَنِ الْوَارِثِ وَ بِأَيِّ شَيْ‏ءٍ جَهِلْتُمْ مَا أَنْكَرْتُمْ وَ بِأَيِّ شَيْ‏ءٍ عَرَفْتُمْ مَا أَبْصَرْتُمْ إِنْ كُنْتُمْ مُؤْمِنِينَ.
333. A number of our companions, from Ahmad Bin Muhammad Bin Khalid, from one of our companions, from Muhammad Bin Al-Haysam, from Zayd Abu Al-Hassan who said: I heard Abu Abdullah  saying: ‘The one for whom the facts are established will never stand upon lifeless doubts. He will not stop until he comes to know the ultimate goal, and seeks the (explanation for) the newly emerging issues from the one who speaks from the inheritors , and for which thing you are ignorant of, what you have denied, and by which thing you have come to recognise what you have visualised, if you are Believers’.
