[٣٦٨/١٠] الكافي: محمد بن إسماعيل، عن الفضل بن شاذان، عن حماد بن عيسى، عن ربعي بن عبدالله، عن الفضيل بن يسار قال: سمعت أبا جعفر عليه السلام يقول: العلم علمان: فعلم عند الله مخزون لم يطلع عليه أحدا من خلقه وعلم علمه وملائكته ورسله، فما علمه ملائكته ورسله فإنه سيكون، لا يكذب نفسه ولا ملائكته ولا رسله، وعلم عنده مخزون يقدم منه ما يشاء، ويؤخر منه ما يشاء، ويثبت ما يشاء
10. [10/368] al-Kafi: Muhammad b. Ismail from al-Fadhl b. Shadhan from Hammad b. Isa from Rib’i b. Abdallah from al-Fudhayl b. Yasar who said: I heard Aba Ja’far عليه السلام saying: Knowledge is of two kinds. A knowledge with Allah which is hidden. No one has seen into it among his creation. And a knowledge which He taught His angels and messengers. So as for that which He taught His angels and messengers then it must occur. He does not belie Himself, nor His angels, nor His messengers. As for the hidden knowledge with Him then He brings forward from it what He wills and puts back from it what He wills, and He establishes what He wills.
