He did khidmat in the Zamaan of three Duat(RA)- Syedna Yusuf Najmuddin(RA), Syedna Abdeali Saifuddin(RA) and Syedna Mohammed Ezzuddin(RA). He authored many 'Nasihats'. Syedi Sadiqali saheb's nasihats incorporate much of the bayaan he had heard from Syedna Abdeali Saifuddin (RA). The nasihats (written in D`awat ni zabaan) cover subjects such as the sublimity of the Shari`ah, its laws, history, wisdom and philosophy. There are also references to taawiil and haqiqat. His description of Imam Husain's (a.s.) shahadat is particularly moving. Syedi Sadiqali saheb has also written eloquently and richly in Arabic and Urdu. He was amongst the witnesses to the nas upon Syedna Mohammed Ezzuddin (RA).
