From EgyptSource, arguing this is the best bet for the opposition, where dialogue should become shura (official consultation):
On the first point, the prevailing opinion – which may even be the consensus – is that Shura is mandatory. Hence, in Islam, the ruler must resort to Shura to obtain the opinion of experts, politicians, and scholars. National dialogue, in fact, is a form of Shura. The second point, and this is the crux of the matter, revolves around the results of the Shura — whether this opinion is binding on the ruler or merely “a consultative opinion” (in contemporary jargon) or “a guiding opinion” (in the vocabulary of Islamic jurisprudence). This issue has many nuances, and this article lacks room to address all of them, but the prevailing opinion among jurists and Islamic scholars is that Shura is binding on the ruler. This means that the opinion resulting from consultation or dialogue is a binding opinion on the ruler, and he must enact it regardless of whether the opinion was the consensus or majority opinion of those consulted.
Curious to see if the opposition sees it this way, as an opportunity. Curious further to see if Morsi does, as an obligation.
There is no way around political discourse in Egypt involving Islam. The question for secularists is how much does even useful recourse to Islam establish the playing ground on Islamist footing?
