I was the slave (of Abi'l-Lahm). I asked the Messenger of Allah ﷺ if I could give some charity out of my master's wealth. He said: Yes, and the reward is half and half between you two.  

كُنْتُ مَمْلُوكًا فَسَأَلْتُ رَسُولَ اللَّهِ ﷺ أَأَتَصَدَّقُ مِنْ مَالِ مَوَالِيَّ بِشَىْءٍ قَالَ نَعَمْ وَالأَجْرُ بَيْنَكُمَا نِصْفَانِ  

My master commanded me to cut some meat in strips; (as I was doing it) a poor man came to me and I gave him some of it to eat. My master came to know of that, and he beat me. I came to the Messenger of Allah ﷺ and narrated it to him. He (the Holy Prophet) summoned him and said: Why did you beat him? He (Abi'l-Lahm) said: He gives away my food without being commanded to do so. Upon this he (the Holy Prophet) said: The reward would be shared by you two.  

أَنْ أُقَدِّدَ لَحْمًا فَجَاءَنِي مِسْكِينٌ فَأَطْعَمْتُهُ مِنْهُ فَعَلِمَ بِذَلِكَ مَوْلاَىَ فَضَرَبَنِي فَأَتَيْتُ رَسُولَ اللَّهِ ﷺ فَذَكَرْتُ ذَلِكَ لَهُ فَدَعَاهُ فَقَالَ لِمَ ضَرَبْتَهُ فَقَالَ يُعْطِي طَعَامِي بِغَيْرِ أَنْ آمُرَهُ فَقَالَ الأَجْرُ بَيْنَكُمَا  

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.  

عَنْ مُحَمَّدٍ رَسُولِ اللَّهِ ﷺ فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ ﷺ 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
