Various aspects of Hanafi Fiqh are explained, e.g., taharat, najasat, ghusl, wudu, tayammum, water, satr, women's covering themselves, adhan, iqamat, namaz, traveler's namaz, juma prayer, and music.The Turkish original of the book Se'âdet-i Ebediyye consists of three parts, all of which add up to more than a thousand pages.We have translated most of the book into English and have published six individual fascicles.Se'âdet-i Ebediyye is a book prepared according to the Hanafî Madhhab. There is not a bit of knowledge or word which does not confirm the creed of the Ahl-i Sunnat and Jamâ'at in this book.This is the fourth fascicle. We pray for the help of Allâhu ta'âlâ so that we may have it reach our dear readers.
