«فَخَرَجَتَا عَلَى سُلَيْمَانَ بْنِ دَاوُدَ فَأَخْبَرَتَاهُ، فَقَالَ: ائْتُونِي بِالسِّكِّينِ أَشُقَّهُ بَيْنَكُمَا، فَقَالَتِ الصُّغْرَى: لَا تَفْعَلْ، يَرْحَمُكَ اللَّهُ، هُوَ ابْنُهَا، فَقَضَى بِهِ لِلصُّغْرَى» (Bukhari and Muslim, as printed)
Translation: The two women then brought the matter to Prophet Sulayman son of Dawud, peace be upon them. He asked for a knife, saying he would divide the child between them. The younger woman immediately pleaded that the child not be harmed and said it belonged to the other woman. Sulayman therefore judged in favor of the younger woman.
The younger woman's willingness to surrender her claim rather than endanger the child revealed her maternal concern. The report does not say that the child was actually cut.
