There are an abundance of books on duas, and every generation of scholars and righteous friends of Allah ﷻ have compiled them, but this version is prepared by Mawlana Ashraf Ali Thanawi with emphasis on the authenticity of the sources.
We have also added the famous Hizb al-Bahr supplication of Shaykh Abul-Hasan ash-Shadhili and Zad as-Said (the forty formulae of prayers on the Prophet ﷺ), also compiled by Mawlana Thanawi.
It is our hope and prayer that this collection connects us directly to the Divine and that it becomes a source of nearness to Him.
