Sindh did not want it

When, therefore, Partition came, the Sindhi Muslims were not sure it was the right thing. Mohammed Ibrahim Joyo was sure it was the wrong thing. He wrote the book Save Sind --- from Pakistan. But it was too late. And when refugees from Bihar poured in, and the Sindhi Hindus began to leave, they were sure it was the wrong thing- The atmosphere in Sindh turned funereal. It was as though the rakshasa (demon) was on the prowl and he might devour anybody and anything any time. People spoke very little and in hushed tones. The Muslims were heard saying that Qiamat (end of the world) seemed to be fast approaching.

Within days Jinnah's portrait was off the Sindhi walls. When refugee Muslims wanted to kill Hindus, Sindhi Muslims refused to cooperate. Premier Khuhro himself went out, revolver in hand, to quell the riots. Indeed, the first dispute between the Sindh Government and the Pakistan Government arose when, after the sack of Karachi on 6 January, 1948, the former arrested refugee rioters and recovered looted property from them, and the Centre sided with the rioters. The refugees were heard saying: ``The Sindhi Muslims seem to be born from the urine of the Hindus.''
