The three brothers from Sekhwan, Mian Imam-ud-Din, Mian Khairu-ud-Din, Mian Jamal-ud-Din, were included in the 313 blessed companions that the Promised Messiah (as) listed himself. 

They were devout followers of the Promised Messiah (as) and their mention can be found in several books of the Promised Messiah (as). Even more fortunate they are to have been included in the list along with their family members. Their mother Sharf Bibi and their father Mian Muhammad Siddique also accepted Ahmadiyyat as well as their sister Amir Bibi (more commonly known as Mai Kako). The latter remained in household service of the Promised Messiah and his family.

The three brothers took oath of allegiance on the same day, 23 November, 1889, at the hand of the Promised Messiah (as). A vast number of testimonies from the three brothers make part of the first-hand compilations of the Promised Messiah's biographical accounts.

Notable servants of the Jamaat from the progeny of these brothers are Hazrat Jalal-ud-Din Shams Saheb (son of Mian Imam-ud-din Saheb) and Maulana Qamar-ud-Din Saheb (Son of Mian Khair-ud-Din Saheb).

Hazrat Maulana Jalal-ud-Din Shams Saheb served in various key roles in the Jamaat. A relatively detailed account can be seen in the entry under his name in Ahmadipedia. His son Munir-ud-Din Shams Saheb is currently serving as Additional Wakil-ut-Tasnif and Managing Director of MTA International.

Qamar-ud-Din Saheb was appointed the first president (Sadr) of Majlis Khuddam-ul-Ahmadiyya at its inception in 1938. His son Rashid-ud-Din Qamar played vital role in establishing Majlis Khuddam-ul-Ahmadiyya in the UK and was its pioneering Qaid alongside serving in many other capacities in the Ahmadiyya Muslim Jamaat UK.
