his grandmother Khairah, the wife of Ka'b bin Malik, came to the Messenger of Allah ﷺ with some jewelry belonging to her and said, I am giving this in charity. The Messenger of Allah ﷺ said to her: “It is not permissible for a woman to dispose of her wealth without her husband's permission. Did you ask Ka'b's permission?” She said: “Yes.” So the Messenger of Allah ﷺ sent for Ka'b bin Malik, her husband, and said, “Did you give Khairah permission to give her jewelry in charity?” He said: “Yes.” So the Messenger of Allah ﷺ accepted it from her.
أَنَّ جَدَّتَهُ خَيْرَةَ امْرَأَةَ كَعْبِ بْنِ مَالِكٍ أَتَتْ رَسُولَ اللَّهِ ﷺ بِحُلِيٍّ لَهَا فَقَالَتْ إِنِّي تَصَدَّقْتُ بِهَذَا فَقَالَ لَهَا رَسُولُ اللَّهِ ﷺ لاَ يَجُوزُ لِلْمَرْأَةِ فِي مَالِهَا إِلاَّ بِإِذْنِ زَوْجِهَا فَهَلِ اسْتَأْذَنْتِ كَعْبًا قَالَتْ نَعَمْ فَبَعَثَ رَسُولُ اللَّهِ ﷺ إِلَى كَعْبِ بْنِ مَالِكٍ زَوْجِهَا فَقَالَ هَلْ أَذِنْتَ لِخَيْرَةَ أَنْ تَتَصَدَّقَ بِحُلِيِّهَا فَقَالَ نَعَمْ فَقَبِلَهُ رَسُولُ اللَّهِ ﷺ مِنْهَا
