قال أبو حنيفة: لو لم يبعث الله تعالى رسولا لوجب على العقلاء معرفته بعقولهم.
Abū Ḥanīfah held that even without a messenger being sent, rational people would be obliged to recognize God through their reason.
This position distinguishes knowledge of God from the specific prescriptions of revealed law. The detailed number, times, conditions, and forms of acts of worship are established through revelation. The responsibility of someone who has not received a particular message raises an additional question about communication of proof.
It would therefore be mistaken to infer that reason's establishing one religious truth also establishes all the detailed obligations of ritual law.
The issues are how knowledge is acquired, whether the legal message has reached a person, and which duties require revealed specification.
