The 34-year-old has ended the speculation surrounding his future after penning a one-year deal with the Qatari outfit and following in the footsteps of Fernando Hierro
The former Spain forward is set to depart Schalke after two years in Germany since his release from the Spanish capital, but the identity of his next team was previously unknown.
However, Al Sadd have now announced on their official website that the decorated 34-year-old will arrive on Qatari shores prior to the beginning of the new campaign.
Raul made his name at Real Madrid after making his debut in 1994, before going on to win six Liga titles and a hat-trick of Champions League crowns.
He also became Los Blancos' all-time top scorer with 323 goals over a 16-year spell but joined Schalke two summers ago.
The attacker was also a success in Gelsenkirchen, despite his advancing years, netting a further 40 times, but revealed the current campaign would be his last for the Royal Blues, which ended in the side retiring the No.7 shirt that he had worn.
Raul has scored 71 Champions League goals, ensuring legendary status.
