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 cause 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 .
