May Allaah facilitate the release of this book on time. Till that time I would recommend reading the book "Kitaab Sharh us-Sunnah by Al-Barbahaaree Translated by Br. Abu Talhah Dawud Burbank". It is available on the www.spubs.com homepage for free reading in point-wise form. Also read the first nine parts of the explanation of this beneficial book by Sh. Ahmed an-Najmee rahimahullah by visiting http://www.al-athariyyah.com/aqeedah.html#
This book and the other book Usool us Sunnah of Imaam Ahmed are very beneficial works which should be read again and again to revise the manhaj of Salaf us Salih. With passage of time we sometimes forget some of the basics and these books and their explanations are important to remind us of the Principles of Ahlus Sunnah wal Jamaah.
Memorize the ayaat of the Qur'aan and the ahadeeth and athar so that the knowledge is always with you and you can effectively enjoin the good and forbid the wrong and invite the masses to the Manhaj as-Salaf us Salih with wisdom and beautiful exhortation.
