With the largest population in eastern Sindh, Umerkot district has the highest percentage of Hindu residents in the country at 54.6%, while Tharparkar district has the most Hindus in absolute numbers at 811,507.

Pirzada is historically described as official owners of Sufi mausoleums and shrines in Muslim lands, with their earliest mentions being in Baghdad, Iraq, during the period of the Ilkhanate, Timurids and Mamluks. Often a Pirzada was a descendant of those buried within the tomb they were assigned to, hence most of the Pirzadas are Syeds.
Muslim Rajputs or Musalman Rajpoots are the descendants of Rajputs in the northern regions of the Indian subcontinent who generally are followers of Islam.

Bihari is a demonym given to the inhabitants of the Indian state of Bihar. Bihari people can be separated into three main Indo-Aryan ethnolinguistic groups, Bhojpuris, Maithils and Magadhis. They are also further divided into a variety of hereditary caste groups. In Bihar today, the Bihari identity is seen as secondary to caste/clan, linguistic and religious identity but nonetheless is a subset of the larger Indian identity. Biharis can be found throughout India, and in the neighbouring countries of Nepal, Pakistan and Bangladesh. During the Partition of India in 1947, many Bihari Muslims migrated to East Bengal. Bihari people are also well represented in the Muhajir people of Pakistan because of Partition.

Muslim communities in South Asia have a system of social stratification arising from concepts other than "pure" and "impure", which are integral to the caste system in India. It developed as a result of relations among foreign conquerors, local upper-caste Hindus convert to Islam and local lower-caste converts (ajlaf), as well as the continuation of the Indian caste system by converts. Non-ashrafs are backward-caste converts. The concept of "pasmanda" includes ajlaf and arzal Muslims; ajlaf status is defined by descent from converts to Islam and by pesha (profession). These terms are not part of the sociological vocabulary in regions such as Kashmir and Uttar Pradesh, and say little about the functioning of Muslim society.
Sufism has a history in India evolving for over 1,000 years. The presence of Sufism has been a leading entity increasing the reaches of Islam throughout South Asia. Following the entrance of Islam in the early 8th century, Sufi mystic traditions became more visible during the 10th and 11th centuries of the Delhi Sultanate and after it to the rest of India. A conglomeration of four chronologically separate dynasties, the early Delhi Sultanate consisted of rulers from Turkic and Afghan lands. This Persian influence flooded South Asia with Islam, Sufi thought, syncretic values, literature, education, and entertainment that has created an enduring impact on the presence of Islam in India today. Sufi preachers, merchants and missionaries also settled in coastal Gujarat through maritime voyages and trade.
