Narrated 'Abdullah:

"I took a walk with the Prophet ﷺ on a farm in Al-Madinah, and when he reclined upon a palm-leaf stalk, a group of Jews were passing by. Some of them said, 'We should question him.' Others said: 'Do not question him for he might tell you something that you do not like.' They said to him: 'O Abul-Qasim, narrated to us about the Ruh.' The Prophet ﷺ stood for some time, he raised his head toward the heavens, and I recognized revelation was coming to him, until the revelation ceased. Then he ﷺ said: "The Ruh is one of the things, the knowledge of which is only with my Lord. And of knowledge, you have been given only a little (17:85).'"

حَدَّثَنَا عَلِيُّ بْنُ خَشْرَمٍ، أَخْبَرَنَا عِيسَى بْنُ يُونُسَ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ، قَالَ كُنْتُ أَمْشِي مَعَ النَّبِيِّ ﷺ فِي حَرْثٍ بِالْمَدِينَةِ وَهُوَ يَتَوَكَّأُ عَلَى عَسِيبٍ فَمَرَّ بِنَفَرٍ مِنَ الْيَهُودِ فَقَالَ بَعْضُهُمْ لَوْ سَأَلْتُمُوهُ فَقَالَ بَعْضُهُمْ لاَ تَسْأَلُوهُ فَإِنَّهُ يُسْمِعُكُمْ مَا تَكْرَهُونَ . فَقَالُوا لَهُ يَا أَبَا الْقَاسِمِ حَدِّثْنَا عَنِ الرُّوحِ . فَقَامَ النَّبِيُّ ﷺ سَاعَةً وَرَفَعَ رَأْسَهُ إِلَى السَّمَاءِ فَعَرَفْتُ أَنَّهُ يُوحَى إِلَيْهِ حَتَّى صَعِدَ الْوَحْىُ ثُمَّ قَالَ : (الرُّوحُ مِنْ أَمْرِ رَبِّي وَمَا أُوتِيتُمْ مِنَ الْعِلْمِ إِلاَّ قَلِيلاً ) .

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
