إيقاظ همم أولي الأبصار
للشيخ الإمام صالح بن محمد العمري الشهير بالفلاني
Excellent book of Imam al-Fulaani رحمه الله on the obligation to follow the Qur'an and the Sunnah and the way of the companions, and the warning about the innovation of following the madhhaab of one of the 4 great imams with ardor and fanaticism.
Shaykh al-Albaani رحمه الله praised this book and said, "The study of this book is obligatory for anyone who loves the truth".
Very good edition whose text is transcribed according to a manuscript and whose hadiths are referenced and authenticated according to Shaykh al-Albaani رحمه الله.
