Anas ibn Malik said, "A woman came to 'A'isha and 'A'isha gave her three dates. She gave each of her two children a date and kept one date for herself. The children ate the two dates and then looked at their mother. She took her date and split it into two and gave each child a half of it. The Prophet, may Allah bless him and grant him peace, came and 'A'isha told him about it. He said, 'Are you surprised at that? Allah will show her mercy because of her mercy towards her child.'"

حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، قَالَ: حَدَّثَنَا ابْنُ فَضَالَةَ، قَالَ: حَدَّثَنَا بَكْرُ بْنُ عَبْدِ اللهِ الْمُزَنِيُّ، عَنْ أَنَسِ بْنِ مَالِكٍ: جَاءَتِ امْرَأَةٌ إِلَى عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا، فَأَعْطَتْهَا عَائِشَةُ ثَلاَثَ تَمَرَاتٍ، فَأَعْطَتْ كُلَّ صَبِيٍّ لَهَا تَمْرَةً، وَأَمْسَكَتْ لِنَفْسِهَا تَمْرَةً، فَأَكَلَ الصِّبْيَانُ التَّمْرَتَيْنِ وَنَظَرَا إِلَى أُمِّهِمَا، فَعَمَدَتْ إِلَى التَّمْرَةِ فَشَقَّتْهَا، فَأَعْطَتْ كُلَّ صَبِيٍّ نِصْفَ تَمْرَةٍ، فَجَاءَ النَّبِيُّ صلى الله عليه وسلم فَأَخْبَرَتْهُ عَائِشَةُ فَقَالَ: وَمَا يُعْجِبُكِ مِنْ ذَلِكَ؟ لَقَدْ رَحِمَهَا اللَّهُ بِرَحْمَتِهَا صَبِيَّيْهَا.
