2 - حدثنا محمد بن الحسن بن أحمد بن الوليد رحمه الله قال: حدثنا محمد بن الحسن الصفار، عن أحمد بن محمد بن عيسى، عن محمد بن أبي عمير، عن هشام بن الحكم، قال: قلت لأبي عبد الله عليه السلام: ما الدليل على أن الله واحد؟ قال: اتصال التدبير وتمام الصنع كما قال عز وجل: ﴿لو كان فيهما آلهة إلا الله لفسدتا﴾ .

2. Muhammad ibn al-Hasan ibn Ahmad ibn al-Walid said: Muhammad ibn al-Hasan alSaffar said, on the authority of Ahmad ibn Muhammad ibn `Isa, on the authority of Muhammad ibn Abu `Umayr, on the authority of Hisham ibn al-Hakam that I asked Abu `Abd Allah al-Sadiq : “What is the Proof that Allah is One?” He replied, “The Proof that Allah is One can be seen in the continued management of creation and its perfection in all aspects. As the Mighty and High says: If there had been in them any gods except Allah, they would both have certainly been in a state of disorder.”
