Hariri returned to Beirut on Tuesday after surprisingly resigning on November 4 during a trip to Saudi Arabia.
Lebanon's Hezbollah parliamentary bloc described Hariri's return to Lebanon -- and his subsequent statements -- as "positive".
"Hariri's return and statements indicate that the situation [in Lebanon] is returning to normal," Anadolu quoted a statement issued by the parliamentary bloc as saying.
It went on to express satisfaction over the way President Michel Aoun -- with the support of Parliament Speaker Nabih Berri -- had managed the crisis caused by Hariri's prolonged absence from Lebanon, reported Anadolu.
"We are pleased by the [recent] political developments that came as a result of the Lebanese people's unity and rejection of external dictates. Now we are waiting for major strategic changes in our region following the defeat of the Daesh terrorist group," it added.
Upon his return to Lebanon, Hariri on Wednesday said that he had put his resignation "on hold".
While tendering his resignation, Hariri had accused Iran and its Lebanese ally Hezbollah of sowing 'sedition' in the region and 'meddling' in Arab affairs. He also hinted at an alleged plot to assassinate him.
Hariri was appointed prime minister in late 2016 and headed a 30-member national unity cabinet that included the Shiite militant Hezbollah.
The government has largely succeeded in protecting the country from the effects of the civil war in neighboring Syria.
