Haji Mohamed Mustafa was born in
India to a farming family. He arrived in
Muar, Malaysia in 1950, and began peddling dumplings, from village to village. His son, Mustaq Ahmad, was born in
Uttar Pradesh in 1951 and joined his father Singapore when he was five. As he grew, Ahmad started helping out at his father's food stall, selling tea and bread. Soon he began to sell handkerchiefs at fixed prices, next to his father's food stall, using pocket money given to him by his father to buy the goods he needed. From 23 July 1973, MMSC's branch would operate from 19 Campbell Lane. It mainly sold ready-made clothing and later expanded to sale of electronic items. In 1985, they moved their business to the ground floor of Serangoon Plaza. In 1990, Mustafa; his eldest son, Mustaq Ahmad; and Samsuddin, founded Mohamed Mustafa and Samsudin Co Pte Ltd (MMSCPL),. As their business expanded, they bought a shophouse on Syed Alwi Road. Subsequently, they bought the neighboring units and decided to build a new shopping mall to house their business. It closed and underwent a disinfection thereafter, and was reopened partially on 6 May 2020, after Singapore authorities eased its
preventive measures to contain the spread of the virus. Since the reopening, operating hours were adjusted to 9.30am - 11.30pm daily due to high electricity costs and rental costs, previously it was operated 24 hours. Now they are operating for 24 hours again. On 27 August 2020, Mustaq announced cost-cutting measures which affected the salaries of some workers, and non-renewal of
work permits of its foreign workers. The company had also worked with various unions and government entities to help redeploy its excess workers resulting from the pandemic to other companies, avoiding the necessity of a retrenchment exercise. In 28 October 2025, Mustafa rolled out its online ecommerce website after years of customers' requests. During COVID-19, it lost customers as they were unable to patronise the shopping mall physically. ==Facilities==
