The consitution, to my knowledge, was not formed by Jinnah or in his time.
Of the consitution, he wrote:
Islam had a role to play in the state (i.e. not secular); it was not a state run by clerics (which he refered to as a theocracy). But then, I’m hard pressed to find a single empire/state/kingship/etc in the history of Islam that was run by clerics. Such comments were no doubt to appease his british masters (he was a Gov General, and so a subject of the Empire), who probably had no idea what he was talking about.
The latter part of his speech is often taken out of context to imply he advocated a secular pakistan, rather than convey his notion of the universality of islamic principles.
