Saiyedna Badruddin Hasan bin Wali saheb (aq), the 31st Da’i al-Mutlaq al-Alavi, did khidmat of Saiyedna Ali bin Ibraheem ash-Shaheed (aq) and Saiyedna Zakiyuddin Saheb (aq) whole-heartedly with full dedication and sincerity which gained him the status and rank of Mukaasir in the last days of Saiyedna Ali (aq). He was then ascended to the martabah of Mazoon during the time of Saiyedna Zakiyuddin Saheb (aq).

He is the only Da’i ul-Mutlaq of India who stayed in the basement beneath the ground (called in the vernacular language as taaka) for a long period of 19 years due to the khawf of mukhaalefeen and harsh political circumstances.  He used to carry out the responsibilities of Da’wat through his hudood and accordingly guide the mumineen in the most challenging times when they were under threat by the ferocious enemies.

Sensing the seriousness of the religious scenario in Ahmedabad where the life and livelihood of Alavi mumineen was frequently targeted and subjected to unbearable oppression, Muqaddas Maulaa ordered his Mazoon Saiyedna Ziyauddin saheb to prepare mumineen for the migration towards the peaceful land where the barakat of Da’wat would ascend and the jama’at of mumineen would flourish.  Vadodara, the birth place of Saiyedna Ali Saheb (aq), the place of peace and tranquility, was selected as Daar ul-Hijrah.  Muqaddas Maulaa did wasiyat to 32nd Da’i ul-Mutlaq Saiyedna Ziyauddin saheb that, after his death he should no longer stay in Ahmedabad but migrate to Vadodara along with Da’wat khazaana, ahl-o-ayaal, hudood and mumineen. He instructed him to establish the markaz and seat of Da’wat-e-Haadiyah in Vadodara.

During his stay in taka where he confined himself from the eyes of commoners and only some hudood were aware of his whereabouts, made unparallel composition of qaseedahs (eulogy), maraasi (elegy), naseehat (admonition), fazaa’il (merits) in Arabic language which later came to be known as “Diwaan-e-Hasan”.  It comprises of the details reflecting the contemporary events, political up-downs, relations with Mughal dominion, proof of the truthfulness of Da’wat-e-Alaviyah, merits of Ahl ul-Bayt (as), halaal-o-haraam, allegorical description of the Da’wat of Sauyedna Jalaal, Saiyedna Dawoodain, Saiyedna Safiyuddin, Saiyedna Ali and Saiyedna Zakiyuddin saheb qaddasallaho arwaahahum.

This Diwaan is a great legacy for us as it is a autograph copy written by the mubaarak hands and beautiful khutoot (handwritings) of Muqaddas Maulaa which makes us realize the ilmiyat and ruhaaniyat of Muqaddas Maulaa and refreshes the harshness of the life of that testing time in which our Muqaddas Maulaa stood determined for the cause of haqq and imaan.
