A unique book of the Hazrat Mirza Ghulam Ahmad (as). Another title of this Book is Dafi-ul-Wasawis. The book includes two parts: Urdu and the other in Arabic. The Urdu part was published in 1892, while the Arabic part was published in 1893.

Hazrat Mirza Ghulam Ahmad (as) wrote this book because the Christians were undermining Islam, raised allegations against the Holy Prophet Muhammad (sa) and criticised the Holy Quran. On the other hand, so-called Muslim scholars held such beliefs that supported the views of the Christian clerics which paved the way for proving the supremacy of Jesus (as) over the Holy Prophet Muhammad (sa).

Hazrat Mirza Ghulam Ahmad (as), wrote this book to expound on the Islamic essence and make the beautiful face of Islam and its divine teachings apparent. This book also contains the first writing of Hazrat Mirza Ghulam Ahmad (as) in Arabic, titled at-Tabligh.
