Turkey's prime minister Tayyip Erdogan has moved up to second place, but the Grand Ayatollah Ali Khamenei of Iran has slipped to number three.
He's six places ahead of Indonesia's Susilo Bambang Yudhoyono at number 9.
Then at 18, there's Hasan Nasrallah, the secretary general of Hezbollah. Usra Ghazi compiled the list for Jordan's Royal Islamic Strategic Studies Centre.
The list also includes the ASEAN head, Dr Surin Pitsuwan, and Dr Farhat Hashmi of the NGO Al-Huda International, and the Australian scholar Waleed Aly.
