Thawban reported,

I was standing beside the Messenger of Allah ﷺ when a rabbi from among the Jewish scholars came and said, "Peace be upon you, Muhammad!" I shoved him with a push that nearly knocked him down.He said, "Why did you shove me?"I replied, "Won't you 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 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 in any way if I tell you?"He replied, "I will listen with my ears." So the Messenger of Allah ﷺ poked the ground with a stick he had with him and said, "Ask."The Jewish man asked, "Where will the people be on the Day when the earth is changed into another earth, and the heavens as well?"The Messenger of Allah ﷺ answered, "They will be in darkness, just before the bridge."He asked, "Who will be the first of the people to cross over?"He answered, "The poor among the emigrants."The Jewish man asked, "What will be their welcoming gift when they enter Paradise?"He answered, "The extra lobe of the fish's liver."He asked, "What will be their food after that?"He answered, "The bull of Paradise will be slaughtered for them, the one that used to graze on its outskirts."He asked, "And what will be their drink with it?"He answered, "From a spring there called Salsabil."He said, "You have spoken the truth."

عن ثوبان مولى رسول الله ﷺ قال

كنت قائما عند رسول الله ﷺ فجاء حبر من أحبار اليهود، فقال: السلام عليك يا محمد! فدفعته دفعة كاد يضرع منها. فقال: لم تدفعني؟ فقلت: ألا تقول: يا رسول الله؟ فقال اليهودي: إنما ندعوه باسمه الذي سماه به أهله. فقال رسول الله ﷺ: إن اسمى 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 والسماوات؟ 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 الذي كان يأكل من أطرافها. قال: فما شرابهم عليه؟ قال: من عين فيها تسمى سلسبيلا. قال: صدقت.
