Imam Ahmad Riza Khan (may Allah be pleased with him) had two sons and five daughters. His sons Maulana Hamid Raza Khan (may Allah be pleased with him) [1362/1934] and Maulana Mustapha Raza Khan (may Allah be pleased with him) [1310/1892] are celebrated savants and Saints of Islam. They rendered great services to Islam and the Muslim community in India.
Imam Ahmad Raza was Pir to a small number of disciples and he founded the silsila Rizwiyya, and in November 1925 appointed and ensured its continuity by appointing his eldest son, Hazrat Hamid Raza Khan (may Allah be pleased with him), as his sajjada-nishan and the ceremony took place on the last day of the annual Urs of Sayyid Shah Ale Rasul (may Allah be pleased with him). Imam Ahmad Raza (may Allah be pleased with him) placed his robe (khirqa), received from his Pir Sayyid Shah Ale Rasul (may Allah be pleased with him) on Hazrat Hamid Raza's (may Allah be pleased with him) shoulders, and his own turban (imama) on his head, before reading the authority (sanad) of the sajjada-nishan in Arabic and Urdu. After his death his disciples and followers affirmed their allegiance to Hazrat Hamid Raza Khan (may Allah be pleased with him) as their sajjada-nishan ['the one seated on a prayer carpet'; official successor to a Saint]
