As I was going along with Allah's Apostle ﷺ in a cultivable land and he (the Holy Prophet) was walking with the support of a wood, a group of Jews happened to meet him. Some of them said to the others: Ask him about the Soul. They said: What is your doubt about it? There is a possibility that you may ask him about anything (the answer of) which you may not like. They said: Ask him. So one amongst them asked him about the Soul. Messenger of Allah ﷺ kept quiet and he gave no reply and I came to know that revelation was being sent to him, so I stood at my place and thus this revelation descended upon him:" They ask thee about the Soul. Say: The Soul is by the Commandment of my Lord, and of Knowledge you are given but a little" (xvii. 58).  

بَيْنَمَا أَنَا أَمْشِي مَعَ النَّبِيِّ ﷺ فِي حَرْثٍ وَهُوَ مُتَّكِئٌ عَلَى عَسِيبٍ إِذْ مَرَّ بِنَفَرٍ مِنَ الْيَهُودِ فَقَالَ بَعْضُهُمْ لِبَعْضٍ سَلُوهُ عَنِ الرُّوحِ فَقَالُوا مَا رَابَكُمْ إِلَيْهِ لاَ يَسْتَقْبِلُكُمْ بِشَىْءٍ تَكْرَهُونَهُ فَقَالُوا سَلُوهُ فَقَامَ إِلَيْهِ بَعْضُهُمْ فَسَأَلَهُ عَنِ الرُّوحِ قَالَ فَأَسْكَتَ النَّبِيُّ ﷺ فَلَمْ يَرُدَّ عَلَيْهِ شَيْئًا فَعَلِمْتُ أَنَّهُ يُوحَى إِلَيْهِ قَالَ فَقُمْتُ مَكَانِي فَلَمَّا نَزَلَ الْوَحْىُ قَالَ { وَيَسْأَلُونَكَ عَنِ الرُّوحِ قُلِ الرُّوحُ مِنْ أَمْرِ رَبِّي وَمَا أُوتِيتُمْ مِنَ الْعِلْمِ إِلاَّ قَلِيلاً}  

I was walking along with Allah's Apostle ﷺ in a field of Medina. The rest of the hadith is the same, but there is a slight variation of wording.  

كُنْتُ أَمْشِي مَعَ النَّبِيِّ ﷺ فِي حَرْثٍ بِالْمَدِينَةِ بِنَحْوِ حَدِيثِ حَفْصٍ غَيْرَ أَنَّ فِي حَدِيثِ وَكِيعٍ وَمَا أُوتِيتُمْ مِنَ الْعِلْمِ إِلاَّ قَلِيلاً وَفِي حَدِيثِ عِيسَى بْنِ يُونُسَ وَمَا أُوتُوا مِنْ رِوَايَةِ ابْنِ خَشْرَمٍ  

Abdullah reported that Allah's Apostle ﷺ was reclining against a tree in the garden. The rest of the hadith is the same with a slight variation of wording.  

كَانَ النَّبِيُّ ﷺ فِي نَخْلٍ يَتَوَكَّأُ عَلَى عَسِيبٍ ثُمَّ ذَكَرَ نَحْوَ حَدِيثِهِمْ عَنِ الأَعْمَشِ وَقَالَ فِي رِوَايَتِهِ وَمَا أُوتِيتُمْ مِنَ الْعِلْمِ إِلاَّ قَلِيلاً  

I will never repay you unless you belie Muhammad. I said: I would never belie Muhammad until you die and you are again raised up. He said: When I would be raised up after death, I would repay your debt when I would get my property and children back. Wakiʿ said: This is how Al-Aʿmash has narrated and it was on this occasion that this verse was revealed: "Hast thou seen him who disbelieves in Our message and says: I shall certainly be given wealth and children" (xix, 77) up to "he would come to Us alone" (xix, 80).  

لِي لَنْ أَقْضِيَكَ حَتَّى تَكْفُرَ بِمُحَمَّدٍ قَالَ فَقُلْتُ لَهُ إِنِّي لَنْ أَكْفُرَ بِمُحَمَّدٍ حَتَّى تَمُوتَ ثُمَّ تُبْعَثَ قَالَ وَإِنِّي لَمَبْعُوثٌ مِنْ بَعْدِ الْمَوْتِ فَسَوْفَ أَقْضِيكَ إِذَا رَجَعْتُ إِلَى مَالٍ وَوَلَدٍ قَالَ وَكِيعٌ كَذَا قَالَ الأَعْمَشُ قَالَ فَنَزَلَتْ هَذِهِ الآيَةُ { أَفَرَأَيْتَ الَّذِي كَفَرَ بِآيَاتِنَا وَقَالَ لأُوتَيَنَّ مَالاً وَوَلَدًا} إِلَى قَوْلِهِ { وَيَأْتِينَا فَرْدًا}  

This hadith has been narrated on the authority of Khabbib through another chain of transmitters and the words are. I in the pre-Islamic days used to work as an iron-smith. I did some work for 'As b. Wa'il and came to him for getting the remuneration of my wages.  

عَنِ الأَعْمَشِ بِهَذَا الإِسْنَادِ نَحْوَ حَدِيثِ وَكِيعٍ وَفِي حَدِيثِ جَرِيرٍ قَالَ كُنْتُ قَيْنًا فِي الْجَاهِلِيَّةِ فَعَمِلْتُ لِلْعَاصِ بْنِ وَائِلٍ عَمَلاً فَأَتَيْتُهُ أَتَقَاضَاهُ
