[3] In 1923, he came across an issue of the Urdu weekly Munadi, published in Delhi by Khwaja [[Hassan Nizami) which carried an article about the conquest of Sindh by the young warrior Muhammad Bin Qasim.

It proved a source of inspiration to Diplai and he started contributing to Munadi and Deen-o-Duniya (Urdu) journals regularly.

[5] On the 31st death anniversary of Muhammad Usman Diplai in 2012, many eminent scholars, writers and intellectuals paid tributes to him at an event held at Sindhi Language Authority auditorium including Rasool Bux Palijo who said that Diplai struggled for the promotion of education when Sindh was in the stranglehold of feudal lords and pirs.

[5] Another scholar Fahmida Hussain noted that Diplai was among the few persons in the 20th century to bring about meaningful reforms in the field of education.
