The author has discusses the topic of innovation in Islam. For example,  he proves that celebrating the Prophet’s birthday is not right according to the Qur’an and Sunnah.

In this era of confusion, innovation, and division, it is essential for Muslims to monitor their beliefs and their approach to Islam, so that they may be certain that they are following the path of the Prophet (blessings and peace of Allah be upon him) and the early generation of pious Muslims (the salaf). Without careful attention, a Muslim may live his or her whole life following a deviant path filled with innovation, thinking that he or she is doing the right thing, only to find out – when it is too late – that this path only leads to hell. Islamic Beliefs: A Brief Introduction to the ‘Aqeedah of Ahl as-Sunnah wal-Jamâ‘ah is written in a straightforward style, distilling the knowledge of the scholars and making it accessible to the ordinary Muslim. It touches on the main points of ‘aqeedah (fundamental Islamic beliefs or creed) and explains the main features of the path of the Prophet (peace be upon him) and the early generation, with brief references to deviant groups in order to show the contrast between the path of the Prophet (peace be upon him) and the paths of the deviant groups, between light and darkness, guidance and misguidance. The straightforward approach of this book will allow the reader to follow its arguments and develop a clear picture of the proper approach to and interpretation of the Qur’an and the Sunnah. This is a book which should be on every Muslim’s bookshelf, so that they will have at their fingertips a concise and readily-accessible reference for the basic issues of their religion.
