What a slave spends of his master's wealth
Sahih Muslim
حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ مُحَمَّدٍ، رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ تَصُمِ الْمَرْأَةُ وَبَعْلُهَا شَاهِدٌ إِلاَّ بِإِذْنِهِ وَلاَ تَأْذَنْ فِي بَيْتِهِ وَهُوَ شَاهِدٌ إِلاَّ بِإِذْنِهِ وَمَا أَنْفَقَتْ مِنْ كَسْبِهِ مِنْ غَيْرِ أَمْرِهِ فَإِنَّ نِصْفَ أَجْرِهِ لَهُ " .
Hammam b. Munabbih said: These are some of the a hadith of Muhammad. the Messenger of Allah (ﷺ), transmitted to us on the authority of Abu Huraira. So he narrated one hadith out of them (as this): The Messenger of Allah (ﷺ) said: No woman should observe fast when her spouse is present (in the house) but with his permission. And she should not admit any (mahram) in his house, while he (her husband) is present, but with his permission. And whatever she spends from his earnings without his sanction, for him is half the reward.
