The College of Arms, or Heralds' College, is a royal corporation consisting of professional officers of arms, with jurisdiction over England, Wales, Northern Ireland and some Commonwealth realms. The heralds are appointed by the British Sovereign and are delegated authority to act on behalf of the Crown in all matters of heraldry, the granting of new coats of arms, genealogical research and the recording of pedigrees. The College is also the official body responsible for matters relating to the flying of flags on land, and it maintains the official registers of flags and other national symbols. Though a part of the Royal Household of the United Kingdom, the College is self-financed, unsupported by any public funds.

The law of heraldic arms governs the "bearing of arms", that is, the possession, use or display of arms, also called coats of arms, coat armour or armorial bearings. Although it is believed that the original function of coats of arms was to enable knights to identify each other on the battlefield, they soon acquired wider, more decorative uses. They are still widely used today by countries, public and private institutions and by individuals. The earliest writer on the law of arms was Bartolus de Saxoferrato. The officials who administer these matters are called pursuivants, heralds, or kings of arms. The law of arms is part of the law in countries which regulate heraldry, although not part of common law in England and in countries whose laws derive from English law.
A herald, or a herald of arms, is an officer of arms, ranking between pursuivant and king of arms. The title is commonly applied more broadly to all officers of arms.

Khan Sahib, Qazi Zafar Hussain came from a qadi's family which had, since the 16th century, been prominent among the landed aristocracy of the Soon Valley. He belonged to Awans tribe of ancient repute. He was awarded the title of Khan Sahib by the British Crown. This was a formal title, a compound of khan (leader) and sahib (Lord), which was conferred in Mughal Empire and British India. Although his father, Qazi Mian Muhammad Amjad forbade his descendants to establish Dargah, he was considered Sajjada Nashin by the people of his area. "Sajjada nashins" David Gilmartin asserts, "claimed to be the descendants of the Sufi, 'saints', intermediaries between the Faithful and their God, and this cut against the grain of Islamic orthodoxy ... in kind, of their special religious status, these sajjada nashins had become men of local standing in their own right." However he never claimed to be a Sajjada Nashin. In the Punjab, the sajjada nashin or pir families were not so rich in terms of land as the great land lords of Punjab but these sajjada nashin or pir families exerted great political and religious influence over the people. The British could not administer the area without their help and no political party could win the election without their help.
