Content:  Safina was born in Moscow to Tatar parents. Her mother Rauza Islanova was her trainer when she was younger; while her father is director of the Spartak tennis club in Moscow. Her brother Marat is a former world No. 1 on the ATP Tour. Speaking of growing up in such a successful tennis family, Safina stated: "Being the little sister in such a big tennis family is not an easy situation. Maybe that's why it took me longer to develop. My father is very competitive, but my parents didn't put pressure on me. I wanted to find my identity. I wanted to be something by myself, like being a big player by myself. So at the beginning I was putting too much pressure on myself. But then gradually I found myself, and I learned how to do better with that situation." At age eight, Safina and her family moved to Valencia, Spain, and as a result Safina speaks fluent Spanish as well as Russian and English.

Safina allegedly retired from professional tennis, as announced by her brother Marat Safin, on October 7, 2011: "Dinara has decided to end her career," Safin said. "She has taken the decision relatively well. She considers it just to be the end of a period in her life." Safin said the main reason for his 25-year-old sister's retirement was a chronic back injury. "Everything is all right with her health. She feels good in everyday life, but (the back injury means) she simply can't play tennis professionally any more." However, Dinara Safina herself later that day issued a Twitter message, where she said she had not made any retirement decision yet, and that she needed more time to decide.
