Former president Nelson Mandela remains in a critical condition in hospital, his grandson Mandla Mandela said in Mvezo, in the Eastern Cape, on Thursday.
"My grandfather continues to be stable while in a critical space," he said.
"We are grateful for updates we receive every day from the presidency."
He praised President Jacob Zuma for visiting the elderly statesman, adding that Zuma had been at his grandfather's bedside.
He said military doctors had been rendering services to Mandela to ensure his recovery.
"We will forever be indebted to many South Africans and many in global community who have rendered many prayers and wishes for my grandfather's recovery. We hope for his speedy recovery."
Mandla Mandela said he wanted to focus on Madiba.
"I want to focus on what matters most, being with my grandfather ensuring I can be with him at this moment that he needs us most..."
