Sahih Bukhari Volume 4, Book 60, Hadith 3428

وَقَالَ ‏"‏ كَانَتِ امْرَأَتَانِ مَعَهُمَا ابْنَاهُمَا جَاءَ الذِّئْبُ فَذَهَبَ بِابْنِ إِحْدَاهُمَا، فَقَالَتْ صَاحِبَتُهَا إِنَّمَا ذَهَبَ بِابْنِكِ‏.‏ وَقَالَتِ الأُخْرَى إِنَّمَا ذَهَبَ بِابْنِكِ‏.‏ فَتَحَاكَمَتَا إِلَى دَاوُدَ، فَقَضَى بِهِ لِلْكُبْرَى فَخَرَجَتَا عَلَى سُلَيْمَانَ بْنِ دَاوُدَ فَأَخْبَرَتَاهُ‏.‏ فَقَالَ ائْتُونِي بِالسِّكِّينِ أَشُقُّهُ بَيْنَهُمَا‏.‏ فَقَالَتِ الصُّغْرَى لاَ تَفْعَلْ يَرْحَمُكَ اللَّهُ، هُوَ ابْنُهَا‏.‏ فَقَضَى بِهِ لِلصُّغْرَى ‏"‏‏.‏ قَالَ أَبُو هُرَيْرَةَ وَاللَّهِ إِنْ سَمِعْتُ بِالسِّكِّينِ إِلاَّ يَوْمَئِذٍ، وَمَا كُنَّا نَقُولُ إِلاَّ الْمُدْيَةُ‏.‏

He also said, "There were two women, each of whom had a child with her. A wolf came and took away the child of one of them, whereupon the other said, 'It has taken your child.' The first said, 'But it has taken your child.' So they both carried the case before David who judged that the living child be given to the elder lady. So both of them went to Solomon bin David and informed him (of the case). He said, 'Bring me a knife so as to cut the child into two pieces and distribute it between them.' The younger lady said, 'May Allah be merciful to you! Don't do that, for it is her (i.e. the other lady's) child.' So he gave the child to the younger lady."
