3ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ النَّضْرِ بْنِ سُوَيْدٍ عَنْ عَاصِمِ بْنِ حُمَيْدٍ قَالَ قَالَ سُئِلَ عَلِيُّ بن الحسين (عَلَيْهما السَّلام) عَنِ التَّوْحِيدِ فَقَالَ إِنَّ الله عَزَّ وَجَلَّ عَلِمَ أَنَّهُ يَكُونُ فِي آخِرِ الزَّمَانِ أَقْوَامٌ مُتَعَمِّقُونَ فَأَنْزَلَ الله تَعَالَى قُلْ هُوَ الله أَحَدٌ وَالايَاتِ مِنْ سُورَةِ الْحَدِيدِ إِلَى قَوْلِهِ وَهُوَ عَلِيمٌ بِذاتِ الصُّدُورِ فَمَنْ رَامَ وَرَاءَ ذَلِكَ فَقَدْ هَلَكَ.

3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Nadr ibn Suwayd from ‘Asim ibn Hamiyd who has said the following. “I asked Imam Ali ibn al-Husayn (a.s.) about the Oneness of Allah. The Imam replied, “Allah the Almighty, the Great, the Exalted knew that in the latter times there will be people who would investigate the issues very deeply in a hair splitting manner. Therefore, Allah, the Glorious, has revealed chapter one hundred twelve of the holy Quran that speak of the Oneness of Allah. He has also revealed the verses of the chapter fifty seven of the holy Quran In the Name of God, the Beneficent, the Merciful All that is in the heavens and the earth speak of the glory of God. He is Majestic and All-wise (57:1). To Him belongs the Kingdom of the heavens and the earth. He gives life and causes things to die. He has power over all things (57:2). He is the First, the Last, the Manifest, and the Unseen and He knows all things (57:3). It is He who created the heavens and the earth in six days and then established His Dominion over the Throne. He knows whatever enters into the earth, what comes out of it, what descends from the sky, and what ascends to it. He is with you wherever you may be and He is Well Aware of what you do (57:4). To Him belong the heavens and the earth and to Him all things return (57:5). He causes night to enter into day and day into night. He knows best what all hearts contain (57:6). Whoever would accept any thing otherwise he is destroyed.”
