for example if zayd obeyed or disobeyed god god would not know what would happen to him because he does not know zayd specifically for he is a person and his actions are new after they did not exist. if he does not know the person he does not know his conditions and actions. rather he does not know zayds disbelief or his islam. rather he knows the disbelief and islam of a person absolutely and completely not specifically for individuals. rather it is necessary to say muhammad may god bless him and grant him peace was challenged with prophethood and he did not know in that situation that he was challenged with it. and the same is the case with every specific prophet and he only knows that there are people who challenge with prophethood and that the description of those is such and such. as for the specific prophet in person he does not know him for that is known by the senses and the conditions that come from it.
أن زيد مثلا لو أطاع الله أو عصاه لم يكن الله عالما بما يتجدد من أحواله لأنه لا يعرف زيدا بعينه فإنه شخص وأفعاله حادثة بعد أن لم تكن، وإذا لم يعرف الشخص لم يعرف أحواله وأفعاله بل لا يعلم كفر زيد ولا إسلامه وإنما يعلم كفر الإنسان وإسلامه مطلقا كليا لا مخصوصا بالأشخاص، بل يلزم أن يقال تحدى محمد صلى الله عليه وسلم بالنبوة وهو لم يعرف في تلك الحالة أنه تحدى بها، وكذلك الحال مع كل نبي معين وإنه إنما يعلم أن من الناس من يتحدى بالنبوة وأن صفة أولئك كذى وكذى فأما النبي المعين بشخصه فلا يعرفه فإن ذلك يعرف بالحس والأحوال الصادرة
