According to tempsreel website, thousands of Muslim men and women taking part in the rally shouted slogans in support of forming a government based on Islamic Sharia.
They also objected to efforts aimed at separation of religion and politics.
Carrying black and white banners with Quranic verses written on them, the demonstrators demanded Tunisian officials to take the Islamic Sharia as the main source for drafting the country’s new constitution.
Women attending the rally shouted "Tunisian women want implementation of Islamic Sharia rules.”
One of the demonstrators told the media that Tunisians will not accept a constitution that is not founded on religious principles, or one in which religion and politics are considered separate. "Islam is our religion and the Holy Quran is our constitution,” he added.
Tunisians ousted the former dictator Zine El Abidine Ben Ali in January 2011 in a revolution that had begun in December 2010.
