Kadyrov told the Rossiiskaya Gazeta government daily that polygamy was necessary in the Russian republic of Chechnya, as there were many more women than men, and that they should all be "fixed up."
He also said that if an unmarried young girl or a divorced woman has sexual relations with men in the Muslim republic then "her brother will kill her and her man."
"We have very severe customs," the 32-year-old leader emphasized. "It is better for a woman to be a second or third wife than to be dead. There is no law on this, but I am saying to everyone - whoever has the desire or the opportunity, you need to take a second wife."
However, the paper said that Kadyrov also noted that as polygamy was not allowed by law, he was simply suggesting that Chechen men act in this manner.
"As far as the law goes," he expounded, "prostitution is forbidden by law, yet how many women sell themselves on the streets of Moscow? Thousands of girls are sold every night!"
"We have no prostitution at all [in Chechnya]," he told the paper. "We are very strict on this."
In a wide-ranging interview, he also said that Chechnya had no need of independence from Russia, stating that the republic would be "unable to survive as a separate state."
He also claimed that fugitive Russian tycoon Boris Berezovsky was responsible for the 2006 murder of investigative journalist and Kremlin critic Anna Politkovskaya in Moscow.
"How could our enemies use Politkovskaya most effectively?" he asked. "By killing her. Who did this? I believe it was Berezovsky."
Over a dozen criminal probes have been launched in Russia against Berezovsky, who currently lives in London, including plotting to stage a coup and embezzling $13 million from a leading Russian bank. The British authorities have consistently refused to extradite him to Russia.
