As guidance and good tidings for the believers meaning

*1) Kitab-i-mubin has three meanings: (1) This book presents its teachings and instructions and injunctions plainly; (2) it distinguishes between the Truth and falsehood clearly; and (3) its being a Divine Book is obvious: whoever studies it with open eyes will realize that it has not been composed and forged by the Holy Prophet himself.
*2) That is, the verses themselves are a "guidance" and "good news", because they give guidance and convey good news in a most excellent manner.
