Prime Minister Datuk Seri Najib Razak warned that Malays and Muslims would be destitute if Umno loses its power in ruling the country.
He said he could not imagine what the country would be without Umno.
"I have asked before, what will happen to the Malays and Muslims if Umno loses power?
"In the many words in the Dewan Bahasa dictionary, some said Malays would be defeated, beaten or fall flat.
"But I choose the word that the Malays will be 'terbangsat' (extremely poor) as there are no other words to picture the fate of Malays who'll lose everything," he said in his speech when opening the Padang Besar, Kangar and Arau Umno divisions meeting at Dewan 2020 here yesterday.
He pledged that he would not back off but stay put as Umno president and Prime Minister for as long as Umno members and the rakyat supported him.
Najib said there was no reason Umno could not remain as the ruling party if its members remained united and mature.
He urged the delegates to trust his commitment in serving the party and country, adding that it had never faded despite him being criticised and slandered.
"Have faith that we are on the right track because the blood that flows in me is a true Umno man's blood.
"I won't run away from the struggle and I am confident that I will not destroy the party. My late father built this party," he said.
"What I do is for the betterment of the people. I don't steal the rakyat's properties and break the laws.
"I do not break the laws and I will not take away the rakyat's rights. I will do the best for the party and the country," he said.
Also present at the function were Perlis Mentri Besar Datuk Seri Azlan Man, who is also the Kangar Umno chief, state Umno and Arau chief Datuk Seri Shahidan Kassim and Rubber Industry Smallholders Authority chairman Datuk Zahidi Zainul Abidin who is also the Padang Besar Umno chief.
Later, Najib launched an agricultural integrated photovoltaic project at the Renewable Energy Park in Kampung Wai, Kuala Perlis, near here.
