I found this interesting record on Canadian external afairs website.
"The most striking impression left by Sir Zafrulla Khan was that, despite his use of Western clothes and his air of cosmopolitanism, he is above all a great Muslim leader. Without in any way adopting the approach of a missionary or the attitude of an apostle, he constantly referred in a most felicitous and easy manner to the life and philosophy of the prophet in support of his own ideas and the actions of the Pakistan Government. He felt that the Muslim teachings, which recognize the responsibility of the state for the provision of the necessities for all citizens, provided a strong barrier against the acceptance of Communism. He recognized, however, that the very heavily populated area of East Pakistan maintained so low a standard of living for large sections of the people that, unless economic conditions could be alleviated, the ground was fertile for the seeds of Communist philosophy. The Pakistan Government felt it was, therefore, necessary to take remedial mea*sures because in the words of the prophet, “Destitution is the mother of infidelity.”
