Is it correct to say that the slave girl who said that Allah is in the heaven, is considered a Sahabiyyah by definition, and therefore she is among the Salaf whom we follow?

Ustadh AbdulAziz al-Haqqan

Not just that non of the sahabah disagreed with her, her owner is also a sahabi and he didn't disagree or clarify that there is something wrong. Baraka Allahu feekum.
