Generally regarded as the single most authentic collection of hadiths, Sahih al-Bukhari covers almost all aspects of life in providing proper guidance from the Messenger of Allah. This book is the work of over 16 years by Imam al-Bukhari who before writing any hadith in this book performed two rak'ahs prayer of guidance from Allah and when he was sure of the hadith's authenticity, he wrote it in the book.

The Life, Teachings and Influence of Muhammad ibn Abdul-Wahhaab: This book is not one with a political agenda. It is meant neither to support nor to critique any contemporary regimes or policies. Indeed, the driving force behind this work is much greater and more important than that. It has to do with, first, the religion of Islam as preached by the Prophet (peace and blessings of Allah be upon him) himself and, second, with the honor and rights of an individual Muslim, Muhammad ibn Abdul-Wahhaab.
