[Machine] A Jewish man passed by the Messenger of Allah ﷺ while he was speaking to his companions. The Quraysh said to the Jewish man, "O Jewish man, he claims to be a prophet." The Jewish man responded, "I will ask him about something that only a prophet knows." So he came and sat down, then he asked, "O Muhammad, from what is mankind created?" Muhammad replied, "O Jewish man, mankind is created from both the sperm of men and the sperm of women. As for the sperm of men, it is thick and includes bones and nerves, while the sperm of women is thin and includes flesh and blood." The Jewish man stood up and said, "This is what others before you used to say."

مَرَّ يَهُودِيٌّ بِرَسُولِ اللهِ ﷺ وَهُوَ يُحَدِّثُ أَصْحَابَهُ قَالَ فَقَالَتْ قُرَيْشٌ يَا يَهُودِيُّ إِنَّ هَذَا يَزْعُمُ أَنَّهُ نَبِيٌّ فَقَالَ لَأَسْأَلَنَّهُ عَنْ شَيْءٍ لَا يَعْلَمُهُ إِلَّا نَبِيٌّ قَالَ فَجَاءَ حَتَّى جَلَسَ ثُمَّ قَالَ يَا مُحَمَّدُ مِمَّ يُخْلَقُ الْإِنْسَانُ؟ قَالَ يَا يَهُودِيُّ مِنْ كُلٍّ يُخْلَقُ مِنْ نُطْفَةِ الرَّجُلِ وَمِنْ نُطْفَةِ الْمَرْأَةِ فَأَمَّا نُطْفَةُ الرَّجُلِ فَنُطْفَةٌ غَلِيظَةٌ مِنْهَا الْعَظْمُ وَالْعَصَبُ وَأَمَّا نُطْفَةُ الْمَرْأَةِ فَنُطْفَةٌ رَقِيقَةٌ مِنْهَا اللَّحْمُ وَالدَّمُ فَقَامَ الْيَهُودِيُّ فَقَالَ هَكَذَا كَانَ يَقُولُ مَنْ قَبْلَكَ

[Machine] Abdullah passed by the Messenger of Allah ﷺ and people began to say, "This is the Messenger of Allah." A Jew then said, "If he is the Messenger of Allah, I will ask him about something. If he is a prophet, he will know the answer." So he said, "O Abu Al-Qasim, tell me: is the child created from the man's semen or the woman's semen?" The Messenger of Allah ﷺ replied, "Indeed, the man's semen is white and thick, from which the bones and nerves are formed, and the woman's semen is yellow and thin, from which the blood and flesh are formed."

عَبْدُ اللهِ مَرَّ رَسُولُ اللهِ ﷺ فَجَعَلَ النَّاسُ يَقُولُونَ هَذَا رَسُولُ اللهِ فَقَالَ يَهُودِيٌّ إِنْ كَانَ رَسُولَ اللهِ فَسَأَسْأَلُهُ عَنْ شَيْءٍ فَإِنْ كَانَ نَبِيًّا عَلِمَهُ فَقَالَ يَا أَبَا الْقَاسِمِ أَخْبِرْنِي أَمِنْ نُطْفَةِ الرَّجُلِ يُخْلَقُ الْإِنْسَانُ أَوْ مِنْ نُطْفَةِ الْمَرْأَةِ؟ فَقَالَ «إِنَّ نُطْفَةَ الرَّجُلِ بَيْضَاءُ غَلِيظَةٌ فَمِنْهَا يَكُونُ الْعِظَامُ وَالْعَصَبُ وَإِنَّ نُطْفَةَ الْمَرْأَةِ صَفْرَاءُ رُقَيْقَةٌ فَمِنْهَا يَكُونُ الدَّمُ وَاللَّحْمُ»

"إِنَّ نُطْفَةَ الرَّجُلِ بيْضَاءُ غليظةٌ فَمنْها يكونُ الْعِظَامُ والْعَصَبُ، وإِنَّ نُطْفَةَ المرأةِ صَفْرَاءُ ورقيقةٌ، فمنها يكونُ اللَّحْمُ والدَّمُ" .
