Ayatollah Ruhollah Khomeini has informally notified Morocco that he wants the extradition of exiled Shah Mohammad Reza Pahlavi to face an Iranian revolutionary tribunal for "crimes against the Iranian people," diplomatic sources reported here today.

The sources said King Hassan II undoubtedly will refuse to hand over the shah, a personal friend for many years, to the Iranians, who are likely to sentence the shah to death.

The shah, Empress Farah and three of their children are living in a palace near Rabat as the guests of the king.

Moroccan officials insisted that no formal demand has been received, but said it is likely that one will come soon. Morocco has an extradition agreement with Iran, and it is expected that if Khomeini makes a formal request, Hassan will ask the shah to seek asylum elsewhere.

Earlier this week Morocco formally recognized Khomeini's revolutionary regime and announced Morocco's "determination to continue the longstanding friendship" between the two Islamic nations.

The shah's aides said the monarch has made no decision to abdicate, denying reports that he has decided to step down from the Peacock Throne.

"No decision has been taken by the shah regarding his possible abdication from the throne," a high aide said.

The Moroccan government said it has not received a request for the shah's extradition and termed the press reports "pure speculation."

The shah's entourage termed press reports about his abdication a natural extrapolation of the fact that he has gone into exile.

The shah left Iran for Egypt Jan. 16 on what was described as an indefinite vacation. He has been in Morocco since Jan. 22 at King Hassan's personal invitation. The two met almost daily in Marrakesh, Morocco's winter capital, until the shah moved to Rabat Thursday and Hassan went to Paris.
