'Even the US friends did denounce this unreasonable action,' Ali Larijani said at the Majlis (Parliament) open session on Sunday.
Political figures and international organizations including the United Nations (UN) as well as all the European Union (EU) member states warned the US not to transfer its embassy to holy Quds (Jerusalem).
Larijani said that the US measure taken within the framework of 'an organized plan' with participation of certain countries is aimed at supporting the Zionist regime, normalizing relations with the regime and making the cause of Palestine forgotten.
'None of the former US presidents has taken such an inappropriate move before,' Larijani said.
He urged the Arab League and the Islamic countries to take a practical measure against the US decision to prevent the US from being more impudent.
The least the Islamic nations can do against the US rudeness is to 'suspend political relations with Washington' and 'cut trade' with it, the Majlis speaker said adding, only in this way, the US president may understand that he cannot play with the Muslims' reputation.
'Land of Palestine belongs to the Palestinian nation,' stressed Larijani.
The US made deals with certain Arab countries and took money from them, but sacrificed the Islamic and Arab cause in order to save the Zionist regime, Larijani concluded.
Worshipers across Iran protested on Friday against the US decision and held rallies natiowide.
