While I was standing beside the Messenger of Allah ﷺ one of the rabbis of the Jews came and said: Peace be upon you, O Muhammad. I pushed him backwith a push that he was going to fall. Upon this he said: Why do you push me? I said: Why don't you say: O Messenger of Allah? The Jew said: We call him by the name by which he was named by his family. The Messenger of Allah ﷺ said: My name is Muhammad with which I was named by my family. The Jew said: I have come to ask you (something). The Messenger of Allah ﷺ said: Should that thing be of any benefit to you, if I tell you that? He (the Jew) said: I will lend my ears to it. The Messenger of Allah ﷺ drew a line with the help of the stick that he had with him and then said: Ask (whatever you like). Thereupon the Jew said: Where would the human beings be on the Daywhen the earth would change into another earth and the heavens too (would change into other heavens)? The Messenger of Allah ﷺ said: They would be in darkness beside the Bridge. He (the Jew) again said: Who amongst people would be the first to cross (this bridge).? He said: They would be the poor amongst the refugees. The Jew said: What would constitute their breakfast when they would enter Paradise? He (the Holy Prophet) replied: A caul of the fish-liver. He (the Jew) said. What would be their food alter this? He (the Holy Prophet) said: A bullockwhich was fed in the different quarters of Paradise would be slaughtered for them. He (the Jew) said: What would be their drink? He (the Holy Prophet) said: They would be given drink from the fountain which is named" Salsabil". He (the Jew) said: I have come to ask you about a thing which no one amongst the people on the earth knows except an apostle or one or two men besides him. He (the Holy Prophet) said: Would it benefit you if I tell you that? He (the Jew) said: I would lend ears to that. He then said: I have come to ask you about the child. He (the Holy Prophet) said: The reproductive substance of man is white and that of woman (i. e. ovum central portion) yellow, and when they have sexual intercourse and the male's substance (chromosomes and genes) prevails upon the female's substance (chromosomes and genes), it is the male child that is created by Allah's Decree, and when the substance of the female prevails upon the substance contributed by the male, a female child is formed by the Decree of Allah. The Jew said: What you have said is true; verily you are an Apostle. He then returned and went away. The Messenger of Allah ﷺ said: He asked me about such and such things of which I have had no knowledge till Allah gave me that.

"The Messenger of Allah [SAW] would sit among his Companions and if a stranger came, he would not know which of them was he (the Prophet [SAW]) until he asked. So we suggested to the Messenger of Allah [SAW] that we should make a dais for him so that any stranger would know him if he came to him. So we built for him a bench made of clay on which he used to sit. (One day) we were sitting and the Messenger of Allah [SAW] was sitting in his spot, when a man came along who was the most handsome and good-smelling of all people, and it was as if no dirt had ever touched his garments. He came near the edge of the rug and greeted him, saying: 'Peace be upon you, O Muhammad!' He returned the greeting, and he said: 'Shall I come closer, O Muhammad?' He came a little closer, and he kept telling him to come closer, until he put his hands on the knees of the Messenger of Allah [SAW]. He said: 'O Muhammad, tell me, what is Islam?' He said: 'Islam means to worship Allah and not associate anything with Him; to establish Salah, to pay Zakah, to perform Hajj to the House, and to fast Ramadan.' He said: 'If I do that, will I have submitted (be a Muslim)?' He said: 'Yes.' He said: 'You have spoken the truth,' we found it odd. He said: 'O Muhammad, tell me, what is faith?' He said: 'To believe in Allah [SWT], His Angels, the Book, the Prophets, and to believe in the Divine Decree.' He said: 'If I do that, will I have believed?' The Messenger of Allah [SAW] said: 'Yes.' He said: 'You have spoken the truth.' He said: 'O Muhammad, tell me, what is Al-Ihsan?' He said: 'To worship Allah [SWT] as if you can see Him, for although you cannot see Him, He can see you.' He said: 'You have spoken the truth.' He said: 'O Muhammad, tell me about the Hour.' He lowered his head and did not answer. Then he repeated the question, and he did not answer. Then he repeated the question (a third time) and he did not answer. Then he raised his head and said: 'The one who is being asked does not know more than the one who is asking. But it has signs, by which it may be known. When you see the herdsmen competing in building tall buildings, when you see the barefoot and naked ruling the Earth, when you see a woman giving birth to her mistress. Five things which no one knows except Allah [SWT]. Verily, Allah, with Him (alone) is the knowledge of the Hour up to His saying: 'Verily, Allah is All-Knower, All-Aware (of things).' Then he said: 'No, by the One who sent Muhammad with the truth, with guidance and glad tidings, I did not know him more than any man among you. That was Jibril, peace be upon you, who came down in the form of Dihyah Al-Kalbi.'"

Thereupon the Jew said: Where would the human beings be on the Daywhen the earth would change into another earth and the heavens too (would change into other heavens)? The Messenger of Allah ﷺ said: They would be in darkness beside the Bridge. He (the Jew) again said: Who amongst people would be the first to cross (this bridge).? He said: They would be the poor amongst the refugees. The Jew said: What would constitute their breakfast when they would enter Paradise? He (the Holy Prophet) replied: A caul of the fish-liver. He (the Jew) said. What would be their food alter this? He (the Holy Prophet) said: A bullockwhich was fed in the different quarters of Paradise would be slaughtered for them. He (the Jew) said: What would be their drink? He (the Holy Prophet) said: They would be given drink from the fountain which is named" Salsabil". He (the Jew) said: I have come to ask you about a thing which no one amongst the people on the earth knows except an apostle or one or two men besides him. He (the Holy Prophet) said: Would it benefit you if I tell you that? He (the Jew) said: I would lend ears to that. He then said: I have come to ask you about the child. He (the Holy Prophet) said: The reproductive substance of man is white and that of woman (i. e. ovum central portion) yellow, and when they have sexual intercourse and the male's substance (chromosomes and genes) prevails upon the female's substance (chromosomes and genes), it is the male child that is created by Allah's Decree, and when the substance of the female prevails upon the substance contributed by the male, a female child is formed by the Decree of Allah. The Jew said: What you have said is true; verily you are an Apostle. He then returned and went away. The Messenger of Allah ﷺ said: He asked me about such and such things of which I have had no knowledge till Allah gave me that. (Using translation from Muslim 315a)   

أَنَّ ثَوْبَانَ مَوْلَى رَسُولِ اللهِ ﷺ قَالَ كُنْتُ قَائِمًا عِنْدَ رَسُولِ اللهِ ﷺ فَجَاءَ حَبْرٌ مِنْ أَحْبَارِ الْيَهُودِ فَقَالَ السَّلَامُ عَلَيْكَ يَا مُحَمَّدُ قَالَ فَدَفَعْتُهُ دَفْعَةً كَادَ يُصْرَعُ مِنْهَا فَقَالَ الْيَهُودِيُّ لِمَ دَفَعْتَنِي؟ فَقُلْتُ أَلَا تَقُولُ يَا رَسُولَ اللهِ قَالَ الْيَهُودِيُّ إِنَّمَا نَدْعُوهُ بِاسْمِهِ الَّذِي سَمَّاهُ بِهِ أَهْلُهُ فَقَالَ رَسُولُ اللهِ ﷺ إِنَّمَا اسْمِي الَّذِي سَمَّانِي بِهِ أَهْلِي مُحَمَّدٌ قَالَ الْيَهُودِيُّ جِئْتُ أَسْأَلُكَ عَنْ شَيْءٍ فَقَالَ رَسُولُ اللهِ ﷺ أَيَنْفَعُكَ شَيْءٌ إِنْ حَدَّثْتُكَ قَالَ أَسْمَعُ بِأُذُنِي فَنَكَتَ رَسُولُ اللهِ ﷺ بِعُودٍ مَعَهُ ثُمَّ قَالَ سَلْ فَقَالَ الْيَهُودِيُّ أَيْنَ يَكُونُ النَّاسُ يَوْمَ تُبَدَّلُ الْأَرْضُ غَيْرَ الْأَرْضِ وَالسَّمَاوَاتُ؟ فَقَالَ رَسُولُ اللهِ ﷺ هُمْ فِي الظُّلْمَةِ دُونَ الْجِسْرِ قَالَ فَمَنْ أَوَّلُ النَّاسِ إِجَازَةً؟ قَالَ فُقَرَاءُ الْمُهَاجِرِينَ قَالَ الْيَهُودِيُّ فَمَا تُحْفَتُهُمْ حِينَ يَدْخُلُونَ الْجَنَّةَ؟ قَالَ زِيَادَةُ كَبِدِ النُّونِ قَالَ فَمَا غِذَاؤُهُمْ عَلَى إِثْرِهَا؟ قَالَ يُنْحَرُ لَهُمْ ثَوْرُ الْجَنَّةِ الَّذِي كَانَ يَأْكُلُ مِنْ أَطْرَافِهَا قَالَ فَمَا شَرَابُهُمْ عَلَيْهِ؟ قَالَ مِنْ عَيْنٍ فِيهَا تُسَمَّى سَلْسَبِيلًا فَقَالَ صَدَقْتَ قَالَ وَجِئْتُ أَسْأَلُكَ عَنْ شَيْءٍ لَا يَعْلَمُهُ أَحَدٌ مِنْ أَهْلِ الْأَرْضِ إِلَّا نَبِيٌّ أَوْ رَجُلٌ أَوْ رَجُلَانِ قَالَ أَيَنْفَعُكَ إِنْ حَدَّثْتُكَ قَالَ أَسْمَعُ بِأُذُنِي قَالَ جِئْتُ أَسْأَلُكَ عَنِ الْوَلَدِ؟ فَقَالَ النَّبِيُّ ﷺ مَاءُ الرَّجُلِ أَبْيَضُ وَمَاءُ الْمَرْأَةِ أَصْفَرُ فَإِذَا عَلَا مَنِيُّ الرَّجُلِ مَنِيَّ الْمَرْأَةِ أَذْكَرَا بِإِذْنِ اللهِ تَعَالَى وَإِذَا عَلَا مَنِيُّ الْمَرْأَةِ مَنِيَّ الرَّجُلِ آنَثَا بِإِذْنِ اللهِ فَقَالَ صَدَقْتَ وَإِنَّكَ لِنَبِيٌّ ثُمَّ انْصَرَفَ فَقَالَ النَّبِيُّ ﷺ لَقَدْ سَأَلَنِي هَذَا عَنِ الَّذِي سَأَلَنِي عَنْهُ وَمَا لِي بِشَيْءٍ مِنْهُ عَلِمٌ حَتَّى آتَانِي اللهُ بِهِ
