Since 1110 AH/ 1699 AD, three centuries has passed and 12 Alavi missionaries (da’is) have so far served the holy mission of Allaah with peace and prosperity. Vadodara is the place of moderate peace-loving people with moderate climatic conditions. Its soil has the essence of producing the men of wisdom and intellectuality. It is a distinction for Alavi Bohras that as many as 12 missionaries with a gap of 20 years when 35th Da’i carried on the mission in Surat (1158-1178 AH/1745-1764 AD), have served their spiritual responsibilities from a single city and in a single house for such a long period. This distinction reaches to a new level of supremacy from the fact that the foundation of the place which is now the residence of Saiyedna is more than 300 years old where all 12 da’is stayed in their respective periods of Da’wat and now it is showered by the bliss of angelic presence of these da’is. This holy residence (Devdi Mubaarak) houses in it, an unparallel and priceless treasures of Faatimi-Taiyebi literature. It has the library of 450 Arabic and Persian manuscripts (MSS-makhtootah), some of them around 500 yrs old.
When their 32nd Da’i-e-Mutlaq Saiyedna Ziyauddin Jivabhai migrated to Vadodara, he took all the valuable manuscripts with him which was there in the possession of Alavi da’is in Ahmedabad. In Vadodara, he first built a beautiful mosque with 7 pillars and 21 arches. He pioneered to build a separate street (mohalla) for Alavi Bohras. He built a mosque at the entrance of mohalla and kept his residence in the middle of it. He then meticulously preserved those manuscripts and maintained this legacy for posterity. There are also autograph copies chiefly transcribed by the Alavi missionaries (da’is) making it a unique treasure house and a rich traditional heritage. These manuscripts are mainly on Faatimi jurisprudence (fiqh), history (akhbaar), doctrines (aqaa'id), facts and realities (haqaa'iq), lectures (majaalis), succession in Prophets and their progeny with propagation of Nass, refutation of false sects, religious sciences, poetry, biographies, admonitions and prayers and on comparative studies. They all are painstakingly preserved, carefully maintained, and periodically copied by Ma’zoon-e-Mutlaq himself, who is next to Saiyedna andby his selected pupils under strict permission and supervision. These manuscripts are not merely for the purpose of storage and preservation or to boast of this legacy, but it is regularly read, taught and literary works are carried out by translating different topics into Lisaan ud-Da’wat. This is done carefully so as to make its complexity easier for a common Alavi to comprehend.
In Vadodara, Alavi Bohras have 4 mosques, 4 community halls, 4 mausoleums in which there are tombs (quboor) of 11 Alavi da’is. They also have a sectarian religious school named as Madrasah Taiyebiyah. The need of a separate guest-house has not yet felt as every Alavi Bohras who stay in other cities or countries have their own house or they have their close relatives in Vadodara. If a problem of staying arises to anyone there is a facility in the community hall, but this seldom happens. Between the period of 1405-1420 AH/1985-2000 AD, the families who were staying in a single house in Badri Mohalla, planned to shift to a new place in a bungalow or flat as the families grew with new marriages. Saiyedna directed these families to build new houses in one locality and named it as "Taiyebi Park" to protect Alavi culture and social relations. During this period many families shifted to Ajwa Road and Fatehgunj in Vadodara to form new Alavi neighbourhood with mosque and madrasah. The place (jamaa’at-khaana)where the food for lunch or dinner is prepared has a strong historical significance and spiritual attachment. The food has a special taste and aroma which one cannot find anywhere. This place is near the Main Mosque and was frequented by all the late Alavi da’is who had a food there and blessed the followers with heartfelt supplications (du’a). Today Saiyedna and his assembly members sit on the same blessed place for meals of feast and funeral.
