Allahu Akbar

Allahu Akbar is the most common slogan of God among Muslims. Every prayer begins with the takbirat al-ihram, meaning “Allahu Akbar.” The adhan, which is referred to as the slogan of monotheism in Islam, begins and ends with “Allahu Akbar” which means “God is the greatest.”
“Allahu Akbar” has been the slogan of all Muslims from the beginning of Islam till now. This monotheist call was one of the important slogans of the Iranian people in the Islamic Revolution. This slogan was first used by the Iranian people after the end of the prayers of Eid al-Fitr on September 4, 1978.
Three days later, when the Shah’s regime had prevented people from demonstrating in Tehran and 11 other cities, on the first night of Muharram of that year, which was 1 December 1978, while the military was in power, people went to the roof of the house and used the slogan “Allahu Akbar” The Shah’s soldiers were afraid of this and fired without aiming, and many were martyred and injured.
The prime minister, who announced the military government, was called “General Gholamreza Azhari,” and the next day in the parliament he said: “The slogans which were used last night were announced by cassette tapes and there were no people.”
On Tasu’a, on December 10, 1978, people had a big demonstration that, answered Azhari, people said: “Azhari you can again say that our demonstration is a demonstration of cassette players but be aware that cassette players can’t walk and can’t take part in demonstrations!”
On February 1, 1979, when Ayatollah Khomeini spoke in Behesht-e Zahra, in order to confirm his speeches, the people said, takbir “Allahu Akbar, Allahu Akbar, Allahu Akbar.”
After the victory of the Islamic Revolution, people used this slogan in the Iran-Iraq War and during the Friday prayers and at various demonstrations, and this slogan remained forever.
