The Prophet ﷺ taught that if an unmarried girl stays silent when asked about a marriage proposal, her silence is understood as consent because she's too shy to verbally say "yes." The silence being referred to is silence from shyness, not silence from fear or being forced. This silence must also be without any indication of refusal, no crying, anger, or anything that shows she's unwilling. If she shows any sign of disagreement, whether through words or body language, that's not consent and the marriage cannot go forward. But this doesn't mean a girl can be pressured into staying quiet. Rather, the hadith shows how the Prophet ﷺ respected the modest nature of young women while still making absolutely sure her consent was real and freely given, not forced.
