There are two distinct tenets in Islam

First is the commands of God and the second is his WILL

God’s commands are in the Quran as the

LAW OF NATURE

But his WILL can be known only through his (God) his Wisdom (Hikma)

His Will cannot be known from religious knowledge, following  commands, sharia, tafsir, learning the tales and stories of prophets and sahabas, taking the literal interpretation of magic stories in the Quran, Islamic theories and principles

His Will cannot be known by learning the hadith of prophets and sahabas and the hadith narrators  

His Will cannot be known by reading and reciting the Quran, its tafsir, learning the hadith or learning the experiences of prophets and sahabas because it is not your experience

His Will cannot be known by believing and worshiping a God because God knows your belief is consistent and your God know he doesnt come to your mind when you worship him

His Will cannot be known by reading Sahih Buhary, sahih muslim, Tirmidi or reading the hadith of Abu Huraira

His Will cannot known by continuously repenting and earning the so-called rewards

His Will cannot be known by your yakeen or the pronouncement of shahada

His will cannot be know by following the secondary sunnah of Muhammed

His Will cannot be known by becoming a moulavi, mufti, ash sheikh or an Alim

However 

God wants man to do good and eschew evil 

But it is because of his Will the good and evil exist 

His Will is not limited to a community following Islam

His Will is unlimited to all mankind following humanity

His Will can be known by learning the purpose of your birth

His Will can be known by serving humanity

His Will can be known by learning the uniformity within the diversity (Oneness of God) 

His Will can be known by knowing your own self (nafs) 

Man arafa nafsahu, fakad arafa Rabbahu

By knowing your own self, Man discover the truth – Quran 5.83

His Will can be known only through Self Realizing your own self
