In seventh-century Damascus, Imam an-Nawawi gathered forty-two hadiths he judged to be the foundations of the entire religion ? on intention, sincerity, mercy, lawful earning, and trust in Allah ? drawn largely from Bukhari and Muslim. Few books in Islamic history have been memorized and taught more widely. This edition presents the complete collection with the Imam's own introduction, a six-week reading companion, study boxes with a practice for every hadith, verified citations, and an index.
