According to this piece in Asharq Al-Awsat:

The Iranian government's pledge of 500 million dollars to Hezbollah has angered many Iranians who say they are still awaiting money to help rebuild their homes that were damaged by wars and natural disasters, informed sources told Asharq Al-Awsat.

...“Informed sources” told Asharq Al-Awsat that spontaneous demonstrations were staged in Bam and in Khuzestan on Friday as protesters shouted slogans critical of Hezbollah and the government. They were demanding their homes be rebuilt instead of the government intervening in Lebanese affairs.

And from the same piece, here's Hezbollah's contribution to the cease fire:

Elsewhere, Hezbollah's representative in Iran has ruled out the disarmament of their Lebanese counterparts and said the group will buy new weapons if necessary.

"There will not be disarmament, the UN resolution has not demanded that either," Abdullah Safieddin told Shargh newspaper in an interview published Monday, on the eighth day of a UN-brokered ceasefire to end the month-long Israeli offensive in Lebanon aimed at crippling Hezbollah.

However, UN Resolution 1701 which laid out the ceasefire calls for the disarmament of all armed groups in Lebanon and prohibits any sales or supply of arms and related materiel to Lebanon except as authorized by its government.
