The book is a collection of supplications taught by the Messenger of Allah, peace be upon him. It has been very popular text and translated in many languages; it is the first time that it is presented in English translation. Some of the supplications which were not based on authentic narrations have been dropped. The book is useful for all those who are interested in approaching Allah Almighty and seek His help in their affairs.
The original has been edited, items with 'unknown sources' redacted. Major letdown: tThere is no table of contents, which is surprising from Darusssalam. The font is pretty tiny, especially the arabic. One good thing is that there is transliteration, which is an improvement. I liked the original book, but could not find it anywhere online.
Good to read
