ok Jinnah never wanted Pakistan to be secular, the speech you people usually refer to, its record does not exist, the BBC, radio Pakistan, and Indian state Radio have no record whatsoever of the speech. oh and here is another speech of Jinnah's for you:
"...I shall watch with keenness the work of your Research Organization in evolving banking practices compatible with Islamic ideas of social and economic life. The economic system of the West has created almost insoluble problems for humanity and to many of us it appears that only a miracle can save it from disaster that is not facing the world. It has failed to do justice between man and man and to eradicate friction from the international field. On the contrary, it was largely responsible for the two world wars in the last half century. The Western world, in spite of its advantages, of mechanization and industrial efficiency is today in a worse mess than ever before in history. The adoption of Western economic theory and practice will not help us in achieving our goal of creating a happy and contended people. We must work our destiny in our own way and present to the world an economic system based on true Islamic concept of equality of manhood and social justice. We will thereby be fulfilling our mission as Muslims and giving to humanity the message of peace which alone can save it and secure the welfare, happiness and prosperity of mankind..." at State Bank's inauguration.
On February 1948, in a radio broadcast to the people of the United States of America, he spoke of Islamic system of government to be adopted in Pakistan. He said:-
“The constitution of Pakistan has yet to be framed by the Pakistan Constituent Assembly. I do not know what the ultimate shape of this constitution is going to be, but I am sure that it will be of a democratic type, embodying the essential principles of Islam. Today they are as applicable in actual life as they were 1,300 years ago. Islam and its idealism have taught us democracy. It has taught equality of man, justice and taught us democracy. We are the inheritors of these glorious traditions and are fully alive to our responsibilities and obligations as framers of the future constitution of Pakistan.”
On February 14, 1948, in Sibi (Pakistan) on an annual gathering known as ‘Sibi Darbar’, Muhammad Ali Jinnah proclaimed:-
“In proposing this scheme, I have had one underlying principle in mind, the principle of Muslim democracy. It is my belief that our salvation lies in following the golden rule of conduct set for us by our great lawgiver the Prophet of Islam. Let us lay the foundations of our democracy on the basis of truly Islamic ideals and principles.”
