 ٢ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ مُحَمَّدِ بْنِ أَبِي عُمَيْرٍ عَنْ مَنْصُورِ بْنِ يُونُسَ وَسَعْدَانَ بْنِ مُسْلِمٍ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلام) قَالَ سَمِعْتُهُ يَقُولُ إِنَّ الارْضَ لا تَخْلُو إِلا وَفِيهَا إِمَامٌ كَيْمَا إِنْ زَادَ الْمُؤْمِنُونَ شَيْئاً رَدَّهُمْ وَإِنْ نَقَصُوا شَيْئاً أَتَمَّهُ لَهُمْ.
 2. Ali ibn Ibrahim has narrated from his father from Muhammad Ibn Abi ‘Umayr from Mansur ibn Yunus and Su‘dan ibn Muslim from Ishaq ibn ‘Ammara from abu ‘Abdallah  who has said the following. “I heard the Imam  saying, ‘The earth is never left without an Imam so that if the believers would add any thing it would be brought back and if they would reduce anything it would be completed.”
