17:85
وَيَسْـَٔلُونَكَ عَنِ ٱلرُّوحِ ۖ قُلِ ٱلرُّوحُ مِنْ أَمْرِ رَبِّى وَمَآ أُوتِيتُم مِّنَ ٱلْعِلْمِ إِلَّا قَلِيلًۭا
And they ask you, [O Muhammad], about the soul. Say, "The soul is of the affair of my Lord. And mankind have not been given of knowledge except a little."

Ibn Kathīr (abridged)
The Ruh (spirit)
Al-Bukhari recorded in his Tafsir of this Ayah that `Abdullah bin Mas`ud said, "While I was walking with the Prophet on a farm, and he was resting on a palm-leaf stalk, some Jews passed by. Some of them said to the others, `Ask him about the Ruh.' Some of them said, `What urges you to ask him about that' Others said, `Do not ask him, lest he gives you a reply which you do not like.' But they said, `Ask him.' So they asked him about the Ruh. The Prophet kept quiet and did not give them an answer, and I knew that he was receiving revelation, so I stayed where I was. When the revelation was complete, the Prophet said:

(And they ask you concerning the Ruh (the spirit). Say: "The Ruh (the spirit) is one of the things, the knowledge of which is only with my Lord...") This context would seem to imply that this Ayah was revealed in Al-Madinah, and that it was revealed when the Jews asked him this question in Al-Madinah, although the entire Surah was revealed in Makkah. This may be answered with the suggestion that this Ayah may have been revealed to him in Al-Madinah a second time, after having previously been revealed in Makkah, or that he was divinely inspired to respond to their question with a previously-revealed Ayah, namely the Ayah in question. Ibn Jarir recorded that `Ikrimah said, "The People of the Book asked the Messenger of Allah ﷺ about the Ruh, and Allah revealed:
وَيَسْـَلُونَكَ عَنِ الرُّوحِ
(And they ask you concerning the Ruh...) They said, `You claim that we have only a little knowledge, but we have been given the Tawrah, which is the Hikmah,
