 ٨ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ يُونُسَ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِي يَعْقُوبَ إِسْحَاقَ بْنِ عَبْدِ الله عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلام) قَالَ إِنَّ الله خَصَّ عِبَادَهُ بِ‏آيَتَيْنِ مِنْ كِتَابِهِ أَنْ لا يَقُولُوا حَتَّى يَعْلَمُوا وَلا يَرُدُّوا مَا لَمْ يَعْلَمُوا وَقَالَ عَزَّ وَجَلَّ أَ لَمْ يُؤْخَذْ عَلَيْهِمْ مِيثاقُ الْكِتابِ أَنْ لا يَقُولُوا عَلَى الله إِلا الْحَقَّ وَقَالَ بَلْ كَذَّبُوا بِما لَمْ يُحِيطُوا بِعِلْمِهِ وَلَمَّا يَأْتِهِمْ تَأْوِيلُهُ.
 Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Yunus (ibn ’Abd al-Rahman) from abu Ya’qub Ishaq ibn ‘Abdallah from abu ‘Abdallah  who has said the following. “Allah has addressed His servants in two verses of the holy Quran very particularly: Did they not make a covenant (with God) in the Book not to speak any thing other than the Truth about God and to study its contents well? They call a lie something that is beyond the limit of their knowledge and whose interpretation has not yet been revealed . .” (10:39)
