"It is not permissible for a woman to give a gift from her wealth, once her husband has marital authority over her." This is the wording of (one of the narrators) Muhammad.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَجُوزُ لاِمْرَأَةٍ هِبَةٌ فِي مَالِهَا إِذَا مَلَكَ زَوْجُهَا عِصْمَتَهَا اللَّفْظُ لِمُحَمَّدٍ  

"When the Messenger of Allah conquered Makkah, he stood up to address (the people) and said in his Khutbah: 'It is not permissible for a woman to give (a gift) except with her husband's permission.'"  

لَمَّا فَتَحَ رَسُولُ اللَّهِ ﷺ مَكَّةَ قَامَ خَطِيبًا فَقَالَ فِي خُطْبَتِهِ لاَ يَجُوزُ لاِمْرَأَةٍ عَطِيَّةٌ إِلاَّ بِإِذْنِ زَوْجِهَا  

"The delegation of Thaqif came to the Messenger of Allah, bringing a gift with them. He said: 'Is it a gift or charity?' If it was a gift it would be for the sake of the Messenger of Allah and to have their needs met, and if it was charity then it would be in the cause of Allah. They said: 'It is a gift.' So he accepted it from them, and sat with them, and they asked questions, until he prayed Zuhr with 'Asr."  

قَدِمَ وَفْدُ ثَقِيفٍ عَلَى رَسُولِ اللَّهِ ﷺ وَمَعَهُمْ هَدِيَّةٌ فَقَالَ أَهَدِيَّةٌ أَمْ صَدَقَةٌ فَإِنْ كَانَتْ هَدِيَّةً فَإِنَّمَا يُبْتَغَى بِهَا وَجْهُ رَسُولِ اللَّهِ ﷺ وَقَضَاءُ الْحَاجَةِ وَإِنْ كَانَتْ صَدَقَةً فَإِنَّمَا يُبْتَغَى بِهَا وَجْهُ اللَّهِ ﷻ قَالُوا لاَ بَلْ هَدِيَّةٌ فَقَبِلَهَا مِنْهُمْ وَقَعَدَ مَعَهُمْ يُسَائِلُهُمْ وَيُسَائِلُونَهُ حَتَّى صَلَّى الظُّهْرَ مَعَ الْعَصْرِ  

"I was thinking of not accepting gifts except from a Quraishi, an Ansari, a Thaqafi or a Dawsi."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لَقَدْ هَمَمْتُ أَنْ لاَ أَقْبَلَ هَدِيَّةً إِلاَّ مِنْ قُرَشِيٍّ أَوْ أَنْصَارِيٍّ أَوْ ثَقَفِيٍّ أَوْ دَوْسِيٍّ  

"What is this?" It was said: "It was given in charity to Barirah." He said: "It is charity for her and a gift for us."  

أَنَّ رَسُولَ اللَّهِ ﷺ أُتِيَ بِلَحْمٍ فَقَالَ مَا هَذَا فَقِيلَ تُصُدِّقَ بِهِ عَلَى بَرِيرَةَ فَقَالَ هُوَ لَهَا صَدَقَةٌ وَلَنَا هَدِيَّةٌ
