1. 1

   Reason grasps the Creator's existence and perfection, yet cannot on its own determine the details of the worship and law that please Him.

2. 2

   To create man accountable while leaving him without clarification would contradict wisdom and remove the basis of his accountability.

3. 3

   Wisdom therefore entails sending messengers who convey that purpose, supported by signs establishing their truthfulness.

﴿رُسُلًا مُبَشِّرِينَ وَمُنذِرِينَ لِئَلَّا يَكُونَ لِلنَّاسِ عَلَى اللَّهِ حُجَّةٌ بَعْدَ الرُّسُلِ﴾

Acknowledging a wise Creator entails expecting clarification from Him; prophethood is a requirement of wisdom, not an addition to it.
