Thawban said, I was standing beside the Messenger of Allah ﷺ when one of the Jewish rabbis came and said, "Peace be upon you, Muhammad."I shoved him so hard that he nearly fell over.He said, "Why did you push me?"I replied, "Can you not say, 'Messenger of Allah'?"The Jewish man said, "We only call him by the name his family gave him."The Messenger of Allah ﷺ said, "My name is indeed Muhammad, the name my family gave me."The Jewish man said, "I have come to ask you something."The Messenger of Allah ﷺ said to him, "Will it benefit you if I tell you?"He said, "I will hear it with my own ears."The Messenger of Allah ﷺ began poking the ground with a stick he had with him and said, "Ask."The Jewish man asked, "Where will people be on the Day when the earth is changed into another earth, and the heavens as well?"The Messenger of Allah ﷺ replied, "They will be in darkness, before the bridge."He asked, "Who will be the first of people to cross?"He answered, "The poor among the Emigrants."The Jewish man asked, "What will be their welcoming gift when they enter Paradise?"He said, "An extra lobe from the liver of the great fish."He asked, "What will be their meal after that?"He said, "The bull of Paradise that used to graze at its edges will be slaughtered for them."He asked, "And what will they drink with it?"He said, "From a spring there called Salsabeel."He said, "You have spoken the truth."He continued, "I have also come to ask you about something which no one on earth knows except a prophet, or one or two other men."He said, "Will it benefit you if I tell you?"He said, "I will hear it with my own ears."He said, "I have come to ask you about the child."He said, "The man's fluid is white and the woman's fluid is yellow. When they unite, if the man's fluid prevails over the woman's, the child will be male, by Allah's permission. And if the woman's fluid prevails over the man's, the child will be female, by Allah's permission."The Jewish man said, "You have spoken the truth, and you are indeed a prophet." Then he turned and left.The Messenger of Allah ﷺ said, "This man asked me about matters of which I had no knowledge until Allah brought it to me."
كنت قائما عند رسول الله ﷺ فجاء حبر من أحبار اليهود، فقال: السلام عليك يا محمد. فدفعته دفعة كاد يصرع منها، فقال: لم تدفعني؟ فقلت: ألا تقول يا رسول الله. فقال اليهودي: إنما ندعوه باسمه الذي سماه به أهله. فقال رسول الله ﷺ: إن اسمي محمد الذي سماني به أهلي. فقال اليهودي: جئت أسألك. فقال له رسول الله ﷺ: أينفعك شيء إن حدثتك؟ قال: أسمع بأذني، فنكت رسول الله ﷺ بعود معه. فقال: سل. فقال اليهودي: أين يكون الناس يوم تبدل الأرض غير الأرض والسموات؟ فقال رسول الله ﷺ: هم في الظلمة دون الجسر. قال: فمن أول الناس إجازة؟ قال: فقراء المهاجرين. قال اليهودي: فما تحفتهم حين يدخلون الجنة؟ قال: زيادة كبد النون. قال: فما غذاؤهم على إثرها؟ قال: ينحر لهم ثور الجنة الذى كان يأكل من أطرافها. قال: فما شرابهم عليه؟ قال: من عين فيها تسمى سلسبيلا. قال: صدقت. قال: وجئت أسألك عن شيء لا يعلمه أحد من أهل الأرض إلا نبي أو رجل أو رجلان. قال: ينفعك إن حدثتك؟ قال: أسمع بأذني. قال: جئت أسألك عن الولد؟ قال: ماء الرجل أبيض، وماء المرأة أصفر، فإذا اجتمعا فعلا منى الرجل مني المرأة أذكرا بإذن الله، وإذا علا مني المرأة مني الرجل آنثا بإذن الله. قال اليهودي: لقد صدقت، وإنك لنبي، ثم انصرف فذهب فقال رسول الله ﷺ: لقد سألني هذا عن الذي سألني عنه وما لي علم بشيء منه حتى أتاني الله به.
