Sunan an-Nasa'i, Book 34, Hadith 38 (In-Book) ⓘ
It was narrated from 'Amr bin Shu'aib, from his father, from his grandfather, that the Messenger of Allah said: "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.
أَخْبَرَنَا مُحَمَّدُ بْنُ مَعْمَرٍ، قَالَ حَدَّثَنَا حَبَّانُ، قَالَ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، ح وَأَخْبَرَنِي إِبْرَاهِيمُ بْنُ يُونُسَ بْنِ مُحَمَّدٍ، قَالَ حَدَّثَنَا أَبِي قَالَ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ دَاوُدَ، - وَهُوَ ابْنُ أَبِي هِنْدٍ - وَحَبِيبٍ الْمُعَلِّمِ عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَجُوزُ لاِمْرَأَةٍ هِبَةٌ فِي مَالِهَا إِذَا مَلَكَ زَوْجُهَا عِصْمَتَهَا " . اللَّفْظُ لِمُحَمَّدٍ .
