In the name of Allāh, the Most Merciful, the Most Compassionate. Introduction to the New Edition: All praise is due to Allāh, who guided us to this, and we would not have been guided if Allāh had not guided us. Peace and blessings be upon our Messenger Muḥammad, through whose ḥadīth and authentic sunnah we are guided, who is addressed by His saying in the Noble Qurʾān: "And indeed, you guide to a straight path" (Sūrah Ash-Shūrā, verse 52), and upon his family and his noble companions, whom Allāh praised by saying: "And the first forerunners among the Muhājirīn and the Anṣār and those who followed them with good conduct - Allāh is pleased with them and they are pleased with Him, and He has prepared for them gardens beneath which rivers flow, wherein they will abide forever. That is the great attainment" (Sūrah At-Tawbah, verse 100), and upon those who followed them and adhered to their path until the Day of Judgment. As for what follows; before the esteemed readers is the new edition of the first volume of my book "The Series of Authentic Ḥadīths." This edition is distinguished from its predecessors—as is customary with the new editions of all my books—by new benefits, numerous verifications, and strong responses to some who have encroached upon this knowledge
