CAIRO (Reuters) - Egyptian President Mohamed Mursi referred a law allowing the state to issue Islamic bonds to a panel of top Muslim scholars on Sunday, state television said, a step that could complicate the government's plans to pass the legislation.

The parliament led by the Muslim Brotherhood's Freedom and Justice Party approved the law earlier this month and referred it to Mursi, triggering a protest last week by Al-Azhar, the country's leading Islamic authority.

Al-Azhar said its top scholars should have been consulted, as stated in the new, Islamist-tinged constitution passed.

The constitution says that Al-Azhar's Senior Scholars Authority must be consulted on all issues pertaining to the sharia, or Islamic law.
