The couple were part of a group that supported and recruited Islamic State fighters, including individuals that had carried out suicide bomb attacks in Syria, a ministry statement said.
The man`s brother had recently died in a suicide bomb attack and that was why the couple were traveling to Morocco in a hurry, the ministry said without giving further details.
Their son has been put in care, it said.
Authorities are searching the couple`s house in Granada and the investigation remains open.
Spain has arrested 18 people so far this year on charges of being linked to Islamist militants.
