Loose play with his feet from Bono presented Spain with a chance, but Ferran Torres was offside when Jordi Alba lashed in a first time cross.
At the other end, Unai Simon was down to comfortably save Noussaur Mazraouri's long-range effort.
Morocco created two chances at the end of the first half, with Nayef Aguerd heading over after Boufal's cross from the left, before Jordi Alba did just enough to stop Ziyech heading back across goal with Simon back-peddling.
Chances were again at a premium at the start of the second half. Dani Olmo's drive from a narrow angle forced Bon to punch clear, before Spain coach Luis Enrique replaced Gavi and Asensio with Carlos Soler and Morata and Osasuna winger. Abde came on for Boufal for Morocco.
Spain still controlled the ball, and Nico Williams came on for Torres as Spain looked for forward momentum.
