If a lady claims to be the mother of a son

Narrated Abu Huraira:

Allah's Apostle ﷺ said, "There were two women with whom there were their two sons. A wolf came and took away the son of one of them. That lady said to her companion, 'The wolf has taken your son.' The other said, 'But it has taken your son.' So both of them sought the judgment of (the Prophet) David who judged that the boy should be given to the older lady. Then both of them went to (the Prophet) Solomon, son of David and informed him of the case. Solomon said, 'Give me a knife so that I may cut the child into two portions and give one half to each of you.' The younger lady said, 'Do not do so;
may Allah bless you ! He is her child.' On that, he gave the child to the younger lady." Abu Huraira added: By Allah! I had never heard the word 'Sakkin' as meaning knife, except on that day, for we used to call it 'Mudya"

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، قَالَ حَدَّثَنَا أَبُو الزِّنَادِ، عَنْ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " كَانَتِ امْرَأَتَانِ مَعَهُمَا ابْنَاهُمَا، جَاءَ الذِّئْبُ فَذَهَبَ بِابْنِ إِحْدَاهُمَا فَقَالَتْ لِصَاحِبَتِهَا إِنَّمَا ذَهَبَ بِابْنِكِ. وَقَالَتِ الأُخْرَى إِنَّمَا ذَهَبَ بِابْنِكِ. فَتَحَاكَمَتَا إِلَى دَاوُدَ ـ عَلَيْهِ السَّلاَمُ ـ فَقَضَى بِهِ لِلْكُبْرَى، فَخَرَجَتَا عَلَى سُلَيْمَانَ بْنِ دَاوُدَ ـ عَلَيْهِمَا السَّلاَمُ ـ فَأَخْبَرَتَاهُ فَقَالَ ائْتُونِي بِالسِّكِّينِ أَشُقُّهُ بَيْنَهُمَا. فَقَالَتِ الصُّغْرَى لاَ تَفْعَلْ يَرْحَمُكَ اللَّهُ. هُوَ ابْنُهَا. فَقَضَى بِهِ لِلصُّغْرَى ". قَالَ أَبُو هُرَيْرَةَ وَاللَّهِ إِنْ سَمِعْتُ بِالسِّكِّينِ قَطُّ إِلاَّ يَوْمَئِذٍ، وَمَا كُنَّا نَقُولُ إِلاَّ الْمُدْيَةَ.
