Hadith.5520 - Safwan ibn Yahya narrated from 'Is ibn Al-Qasim from Abu Abdullah (as), who said: I asked Imam (as) about an orphan girl - when should her wealth be handed over to her?
Imam (as) said: "When you know that she will neither corrupt it nor waste it."
I then asked Imam (as): "What if she has gotten married?"
Imam (as) said: "Once she marries, the authority of the guardian over her ends."
