"I've received sad news, friends, that Abdulmanap Nurmagomedov has left this world," Kadyrov wrote on Telegram messenger, saying he was expressing the condolences of the "whole Chechen people."
The fighter's father was first hospitalised in April in his native North Caucasus region of Dagestan and was later transferred to a Moscow clinic.
Abdulmanap had been battling health problems since mid-May when he suffered a stroke and was placed into a medically-induced coma. He was initially diagnosed with pneumonia. Khabib later revealed that his father was suffering from heart complications related to the coronavirus and that he had over 20 relatives who had also been infected.
Abdulmanap fell into a second coma less than a week after awakening from the first, but Khabib’s manager Ali Abdelaziz told ESPN in June that he was in a hospital in Moscow and “improving.”
Khabib, the 31-year-old UFC lightweight champion, in May urged people in Dagestan, one of the regions hardest hit by the pandemic, to be "disciplined" and "listen to our doctors."
This week he posted a picture of his tracksuited father at a training session on Instagram with the caption ‘Father’ as followers said they were praying for his recovery.
A week ago the fighter had given an interview to Russian television, saying that his father no longer had the virus but was still in intensive care with damage to his kidneys and heart. He said he was visiting daily although his father was not able to speak to him.
The fighter was due to give a press conference on Saturday that has now been cancelled.
Abdulmanap trained numerous champions in judo and the Russian martial arts discipline sambo.
He began teaching his son fighting moves from the age of three, Komsomolskaya Pravda tabloid reported.
In 2018, Russian President Vladimir Putin had a televised meeting with Khabib and his father, saying that the fighter did not deserve harsh punishment for a post-fight brawl.
Khabib is a two-time Combat Sambo World Champion and the reigning UFC Lightweight Champion. With 28 wins and no losses, he holds the longest active undefeated streak in MMA. As of March 17, 2020, he is #2 in the UFC men's pound-for-pound rankings.
Abdulmanap is survived by his three children, Khabib, Magomed, and Amina.
"It's a very difficult situation. I personally have over 20 relatives... who were in intensive care. Many of them are not with us anymore. Many of my acquaintances are dead," Nurmagomedov said.
Sheikh Hamdan captioned the images with an eagle emoji. Khabib is known as the Eagle.
Cementing his legacy Khabib Nurmagomedov maintained his unbeaten streak with a third-round submission win over interim titleholder Dustin Poirier at the UFC 242 at the iconic The Arena at Yas Island in Abu Dhabi.
