Reza ([ɾeˈzɒː], also spelled Raza, Reda, Redha, Rida, Ridha [rɪˈdˤɑ], Rizah, Rıza [ɾɯˈzɑ], Ridho, Ridlo or Roda; Arabic: رضا‎, Riḍā) is a male given name used commonly in the Muslim world, mainly between Persian-speakers. It comes from Arabic and means contentment. It also appears as a surname.

Rida (Reza) is an Islamic concept rooted in the Qur'an and the practices. This idea of contentment is expressed in two Qur'anic verses which discuss the contentment of Allah with believers and, conversely, of believers with Allah:

Muslims believe that Allah's pleasure with the servant is expressed through his gifts both material and spiritual and the servant's pleasure with Allah is the name of his obedience to Allah's commands and submission to his will. Rida on the part of the human also includes his determination to accept Allah's decree irrespective of whether it is favourable or unfavourable.^{[citation needed]}

Because the Arabic dh sound (comparable to the English th) does not exist in the Persian language, Persian-speakers replace the sound with a z. This pronunciation was also adopted by other languages influenced by Persian, most of all Turkish and Hindustani. In the Maghreb region, the name is spelled Reda, due to the French influence during the colonial times.

Lee continues to be a popular figure in Brazilian entertainment, where she is also known for being an animal rights activist and a vegetarian. She has sold more than 60 million albums worldwide.

Rita Lee was born in São Paulo, Brazil, to an American Brazilian father, descended from the Confederados, a dentist, and a Brazilian mother of Italian ancestry. She was educated in a French language school and became fluent in Spanish, French and Italian, as well as her native Portuguese and the English that her parents spoke at home. She went to college, where she was a colleague of the popular actress Regina Duarte, but she soon left to pursue her musical career.

In 1966 Lee formed the band Os Mutantes with Arnaldo Baptista and Sérgio Dias. The band released five albums between 1968 and 1972. In that time, Lee had also released her first two solo works, although these records were produced with fellow members of Os Mutantes. When the band reformed in 2006, she refused to join, calling the reunion an attempt to "earn cash to pay for geriatry".
