Imam Zayn al-'Abidin's `Treatise on Rights' is the only work attributed to him other than supplications or relatively short sayings and letters. The `Treatise on Rights' elaborates on a well-known saying of the Prophet, which has been transmitted in a rather large number of versions, because he repeated it in many different contexts.
A collection of supplications and whispered prayers composed by the great-grandson of the Prophet (s). Includes supplication for the Coming of the Month of Ramadhan, and supplication for Bidding Farewell to the Month of Ramadhan. At the end there is also the famous Treatise on Rights that explains beautifully the rights in an Islamic point of view.
