[٣٣٩/٢] الكافي: محمد بن يحيى، عن سعد بن عبدالله، عن محمد بن عيسى، عن أيوب بن نوح أنه كتب إلى أبي الحسن عليه السلام يسأله عن الله عزوجل أكان يعلم الاشياء قبل أن خلق الاشياء وكونها أو لم يعلم ذلك حتى خلقها وأراد خلقها وتكوينها فعلم ما خلق عندما خلق وما كون عند ما كون؟ فوقع بخطه: لم يزل الله عالما بالاشياء قبل أن يخلق الاشياء كعلمه بالاشياء بعد ما خلق الاشياء
2. [2/339] al-Kafi: Muhammad b. Yahya from Sa’d b. Abdallah from Muhammad b. Isa from Ayyub b. Nuh that he wrote to Abi al-Hasan عليه السلام asking him about Allah Mighty and Majestic: Did He have knowledge of things before He created the things and brought them into existence or is it that He did not have prior knowledge of them until when He created them and intended their creation and bringing them into existence - so He knew about what He created at the moment of creation and what He brought into existence at the moment of bringing into existence? He wrote in his handwriting: Allah never stopped being knowledgeable about the things before he created the things the same as His knowledge of the things after He had created the things.
