If anyone wish to gain wisdom (Hikma)

The Holy Quran alone is sufficient

Quran 6.114 – 7.52 – 12.111 – 16.89

But

Only a purified can gain it’s wisdom

Purification of the heart not purification by external ablution

Because the meaning of the Holy Quran differs to each persons level of consciousness 

That purified can be born in any faith

I (God) don’t want you to read man made books claiming to be authentic to interpret my wisdom in the Quran

I (God) never said anywhere to refer any book to seek guidance and gain wisdom other than my Holy Quran

I (God) don’t want you to be a blind follower

I (God) want you to become good thinkers

Quran 47.24 – 2.170

Not intellectually but spiritually
