The two leaders met at the presidential complex in the capital Ankara, Turkish presidential sources said.
The lingering Gulf crisis has little impact on Qatar's sovereign wealth fund and the business is going on as usual, Qatar Investment Authority (QIA) Chief Executive Officer HE Sheikh Abdullah bin Mohammed bin Saud al Thani has said, Qatar news agency (QNA) reported Thursday.
The diplomatic crisis between Gulf countries began on June 5, when Saudi Arabia, the United Arab Emirates, Egypt and Bahrain collectively severed diplomatic and transport ties with Qatar, accusing it of supporting terrorism in the region.
Pearl decried Qatar for providing "shelter and unlimited support to Qaradawi", who also has a wildly popular TV show on Sharia law broadcast on the Qatari-funded Al Jazeera network.
In a show of solidarity, Turkey has also sent cargo ships and hundreds of planes loaded with food to break the blockade.
Since the beginning of the Persian Gulf crisis, Qatar has strengthened its relations with other countries especially in the military and defense field.
But that visit ended without any sign of a breakthrough. It was not clear if Al Thani and Kuwait's Sheikh Jaber Al-Mubarak Al-Sabah would meet in Ankara.
Judea Pearl - a Chancellor's Professor at UCLA and the president of the Daniel Pearl Foundation, which promotes cross-cultural understanding - told The Algemeiner on Wednesday that he urged "Jewish leaders to refrain from meeting the emir of Qatar, and thus bestow credibility onto a country that has served as the hub of terrorism-breeding ideology in the past two decades".
Over the last years, Qatar has emerged as Turkey's number one ally in the Middle East, with Ankara and Doha closely coordinating their positions on a number of issues including the Syria conflict where both are staunch foes of President Bashar al-Assad.
Ankara has a military base in Qatar and deployed more troops after the hostilities erupted.
The closure of the base was one of the conditions laid by the Saudi-led bloc for the lifting of the sanctions, which was rejected by Doha.
