Abu Hurairah (May Allah be pleased with him) reported:
Messenger of Allah ﷺ said, "It is not lawful for a woman to observe (voluntary) fasting without the permission of her husband when he is at home; and she should not allow anyone to enter his house without his permission.".

[Al-Bukhari and Muslim].

وعن أبي هريرة رضي الله عنه أيضًا أن رسول الله ﷺ قال؛ " لا يحل لامرأة أن تصوم وزوجها شاهد إلا بإذنه، ولا تأذن في بيته إلا بإذنه" ((متفق عليه وهذا لفظ البخاري)).
