After having founded Qasr-ul-Adab in 1923, Seemab Akbarabadi had in the year 1930 started publication of a literary journal in Urdu from Agra titled Shair; he was its first editor. A few years later i.e. in 1935, in order to concentrate on the other than more important activities of Qasr-ul- Adab, he had handed over the charge of this magazine to Aijaz Siddiqi who carrying forward the tradition of his father remained its editor till 1978 long after the publication of Shair was shifted from Agra to Mumbai in 1947 and Seemab Akbarabadi had in 1951 died in Karachi.
