Giving gifts by a husband to his wife, and by a wife to her husband

Narrated Az-Zuhari:

Ubaidullah bin 'Abdullah told me that 'Aisha had said, "When the Prophet became sick and his condition became serious, he requested his wives to allow him to be treated in my house, and they allowed him. He came out leaning on two men while his feet were dragging on the ground. He was walking between Al-'Abbas and another man." 'Ubaidullah said, "When I informed Ibn 'Abbas of what 'Aisha had said, he asked me whether I knew who was the second man whom 'Aisha had not named. I replied in the negative. He said, 'He was 'Ali bin Abi Talib."

حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا هِشَامٌ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ، قَالَتْ عَائِشَةُ ـ رضى الله عنها ـ لَمَّا ثَقُلَ النَّبِيُّ ﷺ فَاشْتَدَّ وَجَعُهُ اسْتَأْذَنَ أَزْوَاجَهُ أَنْ يُمَرَّضَ فِي بَيْتِي، فَأَذِنَّ لَهُ، فَخَرَجَ بَيْنَ رَجُلَيْنِ، تَخُطُّ رِجْلاَهُ الأَرْضَ، وَكَانَ بَيْنَ الْعَبَّاسِ، وَبَيْنَ رَجُلٍ آخَرَ. فَقَالَ عُبَيْدُ اللَّهِ فَذَكَرْتُ لاِبْنِ عَبَّاسٍ مَا قَالَتْ عَائِشَةُ، فَقَالَ لِي وَهَلْ تَدْرِي مَنِ الرَّجُلُ الَّذِي لَمْ تُسَمِّ عَائِشَةُ قُلْتُ لاَ. قَالَ هُوَ عَلِيُّ بْنُ أَبِي طَالِبٍ.
