Arabic to English Art/Literary Poetry & Literature

Hi everyone,

Does this mean 'her will/desire?' I thought it's only used in the situation of someone writing their will, or if they are dead and left instructions on what they want to happen in their absence. But here, the person is very much still alive.

حينها وبسرّية تامة عهدت بابنها الوحيد لعبد السلام التاجر، ووصيتها أن يساعد ابنها في العثور على والده

Is it more like رغبة here?

Thanks!
