Why were muslims less in civil …

 (i) After the decline of the Non-Cooperation-Khilafat Movement, a large section
of Muslims felt separated from the Congress.
(ii) From the mid-1920s the Congress came to be more visibly associated with
openly Hindu religious nationalist groups like the Hindu Mahasabha.
(iii) This worsened the relations between Hindus and Muslims.
(iv) Each community organised religious processions with militant fervour,
provoking Hindu-Muslim communal clashes and riots in various cities.
(v) Every riot deepened the distance between the two communities.
(vi) Muhammad Ali Jinnah, (leader of the Muslim League) agreed to quit the
demand for separate electorates, if Muslims were guaranteed reserved seats
in the Central Assembly and representation in the Muslim-dominated
provinces (Bengal and Punjab).
(vii) But all hopes were dashed in 1928 when M.R. Jayakar of the Hindu Mahasabha
strongly opposed to compromise.
(viii) In 1930, Sir Muhammad Iqbal, (President of the Muslim League) re-stated the
importance of separate electorates for the Muslims as an important safeguard
for their minority political interests.
