Perhaps the best available book on Muslim Prayer.
It discusses the nature, significance, and value of prayer.
It contains all important prayers with Arabic text, translation and transliteration and short phrases of daily use. Illustrated with photographs.
This book is a short introduction to performing basic Muslim prayers, from physical movement aspects, to what is said during the prayers, as well as the times to say them.
It also gives prayers and sacred sayings relevant to all sorts of other activities.
I am sure there are more extensive and comprehensive books out there, but this is a great book for learning, or at least becoming familiar with the essentials.
