[Machine] A Jewish man passed by the Messenger of Allah ﷺ while he was talking to his Companions. The Quraish said to him, "O Jew, he claims to be a prophet. Ask him about something that only a prophet would know." So, he came and sat down and said, "O Muhammad, from what is man created?" He replied, "O Jew, man is created from both the sperm of the man and the sperm of the woman. As for the sperm of the man, it is thick and from it bones and nerves are formed. And as for the sperm of the woman, it is thin and from it flesh and blood are formed." Then the Jewish man stood up and left. Abu Abdullah Ata ibn As-Sa'ib said, "He had changed."  

مَرَّ يَهُودِيٌّ بِرَسُولِ اللهِ ﷺ وَهُوَ يُحَدِّثُ أَصْحَابَهُ قَالَ قَالَتْ قُرَيْشٌ يَا يَهُودِيُّ إِنَّ هَذَا يَزْعُمُ أَنَّهُ نَبِيٌّ فَقَالَ لَأَسْأَلَنَّهُ عَنْ شَيْءٍ لَا يَعْلَمُهُ إِلَّا نَبِيٌّ فَجَاءَ حَتَّى جَلَسَ فَقَالَ يَا مُحَمَّدُ مِمَّ يُخْلُقُ الْإِنْسَانُ؟ قَالَ يَا يَهُودِيُّ مِنْ كُلٍّ يُخْلَقُ مِنْ نُطْفَةِ الرَّجُلِ وَمِنْ نُطْفَةِ الْمَرْأَةِ فَأَمَّا نُطْفَةُ الرَّجُلِ فَنُطْفَةٌ غَلِيظَةٌ فَمِنْهَا الْعَظْمُ وَالْعَصَبُ وَأَمَّا نُطْفَةُ الْمَرْأَةِ فَنُطْفَةٌ رُقَيْقَةٌ فَمِنْهَا اللَّحْمُ وَالدَّمُ فَقَامَ الْيَهُودِيُّ وَاللَّفْظُ لِأَحْمَدَ قَالَ أَبُو عَبْدِ الرَّحْمَنِ عَطَاءُ بْنُ السَّائِبِ كَانَ قَدْ تَغَيَّرَ
