"Given the heavy failures that the ISIL and other terrorist groups in Iraq and Syria have sustained, we are sure that these groups are nearing the end of their life," Soleimani said, addressing a ceremony on the occasion of the 36th anniversary of the victory of the Islamic Revolution in the Southern province of Kerman on Wednesday.
He said that persuading and organizing the Takfiri streams to impair the face of Islam and creating sedition and civil war among Muslims is the last weapon used by the arrogant powers.
In relevant remarks in October, General Soleimani underlined that the US moves in the region and the terrorist attacks by the ISIL would end in failure.
"I believe that both the US moves and the terrorist acts of the ISIL are doomed to failure because they are not in quest for truth," General Soleimani told reporters in Tehran.
"Their solution will not lead to victory; we have all witnessed in Syria that the measures they adopted did not produce any fruit (for them)," he added.
General Soleimani underlined that the victories gained by Islam and the Islamic Republic of Iran had all been the result of their real quest for truth.
In similar remarks in June, Deputy Secretary-General of Lebanese Hezbollah Resistance Movement Sheikh Naim Qassem said that the US, Israeli and Takfiris' plots had the same character, and were doomed to failure.
Sheikh Qassem said the Takfiri plots had their different forms and tools which aimed at undermining the dignity and pride of the Muslim nations.
He further added that the plots would undoubtedly fall flat, as it was foiled in Lebanon when the Resistance thwarted the Israeli threats in 2000 and 2006.
Over the last few years, Gen Soleimani's role in Iran's foreign affairs has become more public. These days he is the proud face of Iran, the go-to man when a crisis happens.
Iran has been providing advice and counseling to Syria and Iraq to help them in the war on terrorism.
