if it is said that knowing god and his messenger is not enough but rather one must know the attributes of god and know the legal rulings we say as for the attributes of god almighty they are of two types. one type is that it is not possible to know the truthfulness of the messenger and his mission except after knowing him such as his being knowledgeable and able to send. this is known to us through rational evidence as we mentioned. the infallible does not suffice because the one who believes in him by imitation or hearing from his parents does not need a teacher as previously mentioned. and the one who is hesitant about it what does the infallible suffice for him? so he says to him imitate me in that he almighty is able and knowledgeable so he says to him how? i imitate you but my soul does not allow me to imitate muhammad ibn abdullah may god bless him and grant him peace who is the owner of the miracle. if he mentions to him the face of the evidence he returns the statement in it to what has passed in the origin of the existence of the creator and the truthfulness of the messenger without any difference. as for the legal rulings each one must know what he needs in his duties and they are of two types.
فإن قيل لا تكفي معرفة الله ورسوله بل لا بد من معرفة صفات الله ومعرفة الاحكام الشرعية قلنا أما صفات الله تعالى فقسمان قسم لا يمكن معرفة صدق الرسول وبعثته الا بعد معرفته ككونه عالما وقادرا على الارسال فهذا يعرف عندنا بالأدلة العقلية كما ذكرناه والمعصوم لا يغني لان المعتقد له تقليدا او سماعا من ابويه مستغن عن المعلم كما سبق والمتردد فيه ماذا يغني عنه المعصوم أفيقول له قلدني في انه تعالى قادر عالم فيقول له كيف أقلدك ولم تسمح نفسي بتليقد محمد بن عبد الله صلى الله عليه وسلم وهو صاحب المعجزة وإن ذكر له وجه الدليل اعاد القول فيه الى ما مضى في اصل وجود الصانع وصدق الرسول من غير فرق واما الاحكام الشرعية فلا بد لكل واحد من معرفة ما يحتاج اليه في واجباته وهي قسمان
