It is He Who has sent down to you (O dear Prophet Mohammed - peace and blessings be upon him) this Book (the Qur’an) containing the verses that have a clear meaning - they are the core of the Book - and other verses the meanings of which are indistinct; those in whose hearts is deviation pursue the verses having indistinct meanings, in order to turmoil and seeking its (wrongful) interpretation; and only Allah knows its proper interpretation; and those having sound knowledge say, “We believe in it, all of it is from our Lord”; and none accept guidance except the men of understanding.
