Wedlock, Marriage (Nikaah)
Ṣaḥīḥ al-Bukhārī 5195
لاَ يَحِلُّ لِلْمَرْأَةِ أَنْ تَصُومَ وَزَوْجُهَا شَاهِدٌ إِلاَّ بِإِذْنِهِ، وَلاَ تَأْذَنَ فِي بَيْتِهِ إِلاَّ بِإِذْنِهِ، وَمَا أَنْفَقَتْ مِنْ نَفَقَةٍ عَنْ غَيْرِ أَمْرِهِ فَإِنَّهُ يُؤَدَّى إِلَيْهِ شَطْرُهُ
lā yaḥillu lilmarʾah an taṣūma wazawjuhā shāhidun illā biʾidhnihi, walā taʾdhana fī baytihi illā biʾidhnihi, wamā anfaqat min nafaqatin ʿan ghayri amrihi fa-innah yuʾaddā ilayhi shaṭruhu

The full narration
Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "It is not lawful for a lady to fast (Nawafil) without the permission of her husband when he is at home; and she should not allow anyone to enter his house except with his permission; and if she spends of his wealth (on charitable purposes) without being ordered by him, he will get half of the reward
