٣ - حدثنا محمد بن موسى بن المتوكل رحمه الله، قال: حدثنا علي بن إبراهيم قال: حدثنا محمد بن عيسى بن عبيد، عن يونس بن عبد الرحمن، عن عبد الله بن سنان عن أبي عبد الله عليه السلام قال: سألته عن قول الله عز وجل: (فطرة الله التي فطر الناس عليها) ما تلك الفطرة؟ قال: هي الإسلام، فطرهم الله حين أخذ ميثاقهم على التوحيد فقال: (ألست بربكم) وفيه المؤمن والكافر . 
3. Muhammad ibn Musa ibn al-Mutawakkil  said: `Ali ibn Ibrahim said: Muhammad ibn `Isa ibn `Ubayd said, on the authority of Yunus ibn `Abd al-Rahman, on the authority of `Abd Allah ibn Sinan that I asked Abu `Abd Allah al-Sadiq  “What is the nature referred to in the Word of Allah, the Mighty and High: “The nature made by Allah is which He has made men.” He responded, It is Islam. Allah placed this nature in them when He created them and made a covenant with them regarding Divine Unity. Thus, He asked: Am I not your Lord? The covenant encompassed all those who believe and all those who disbelieve.
