Abu Hurairah reported,

The Messenger of Allah ﷺ said, "A woman must not fast while her husband is present except with his permission, nor admit anyone into his house while he is present except with his permission. Whatever she spends from his earnings without his instruction, half of its reward belongs to him."

قال رسول الله ﷺ: لا تصم المرأة ويعلها شاهد إلا بإذنه، ولا تأذن في بيته وهو شاهد إلا بإذنه، وما أنفقت من كسبه من غير أمره فإن نصف أجره له.
