Hadith 449 5ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ عَنِ ابْنِ مُسْكَانَ عَنْ أَبِي بَصِيرٍ عَنْ أَحَدِهِمَا (عَلَيْهما السَّلام) قَالَ قَالَ إِنَّ الله لَمْ يَدَعِ الارْضَ بِغَيْرِ عَالِمٍ وَلَوْ لا ذَلِكَ لَمْ يُعْرَفِ الْحَقُّ مِنَ الْبَاطِلِ.
5. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus from ibn Muskan from Abu Basir from one of them (a.s.), who said: “Allah does not leave the earth without a ‘Alim (scholar). Without this the truth would not be distinguished from falsehood.”
