This book is an English translation of Kitab-al-Adhkar (کتاب الاذکار) by Imam An-Nawwawi.
Kitab al-Adhkar is the definitive compilation of words of remembrance and glorification of (dhikr), and supplicatory prayer to (du’a), the Lord of the Universe, as related from His final Emissary, the Prophet Muhammad (may Allah bless and exalt him). Dhikr and du’a lie at the very heart of the din, the relationship between creature and Creator. As part of the Sunna or Prophetic Way, they are a divinely appointed means of approaching Allah Most High for all our needs, and of making use of all the moments of daily life to strengthen our tawhid, the existential and cognitive Unity that is the hallmark of Muslim spirituality. Also covered are the vital principles of speaking only what is good and avoiding the sins of the tongue.
