Analysis of information sources in references of the Wikipedia article "Allah Bux Soomro" in English language version.
Allah Bux Soomro was a member of the Soomro (Jat) clan of Sindh. The clan held sway over Sindh for more than three centuries after the Ghaznavid period..
However, by 1943, Bakhsh was killed — allegedly by League goons.
On 14th May 1943, Allah Bux Soomro was assassinated by four men, while he was travelling in a tonga in Shaikarpur. 73 years later, his case still remains unsolved, but it's rumoured that his murder was carried out by members of the Muslim League.
However, the book is a tribute to the role of one Muslim leader who steadfastly opposed the Partition of India: the Sindhi leader Allah Bakhsh Soomro. Allah Bakhsh belonged to a landed family. He founded the Sindh People's Party in 1934, which later came to be known as 'Ittehad' or 'Unity Party'. ... Allah Bakhsh was totally opposed to the Muslim League's demand for the creation of Pakistan through a division of India on a religious basis. Consequently, he established the Azad Muslim Conference. In its Delhi session held during April 27–30, 1940 some 1400 delegates took part. They belonged mainly to the lower castes and working class. The famous scholar of Indian Islam, Wilfred Cantwell Smith, feels that the delegates represented a 'majority of India's Muslims'. Among those who attended the conference were representatives of many Islamic theologians and women also took part in the deliberations.
