Burhanuddin issued a dress code, calling for male Bohras to grow a beard and wear a white topi and kurta, and for women to wear a colorful two piece abaya, known formally as a Rida.
This Islamization countered a trend toward assimilation into the larger culture of their ancestors that was also prevalent under his predecessor, Taher Saifuddin and the previous Du'at before them.
The history of this culture can be traced back to the medieval Fatimid dynasty in Egypt.

In 1980 ACE/1401 AH, the Al-Hakim mosque was extensively refurbished in white marble and gold trim by Mohammed Burhanuddin.
Remnants of the original decorations, including stucco carvings, timber tie-beams, and Quranic inscriptions were restored as part of the renovations.
His intent to restore the ancient Al-Hakim Mosque as a place of worship in contemporary times necessitated a lighting solution that provided this important functionality to the mosque and did so in a manner that paid tribute to the Fatimid tradition of illumination and its aesthetics.
The miraculous emergence of the mishkat or small lantern from the niche of the richly decorated façade of Al Jami al Aqmar provided that solution.
The niche in which the lantern motif was found has also been compared to the mihrab niche of Al Azhar mosque, the same also now found in Al-Hakim mosque, which has a central motif that resembles a large lamp or lantern.
