The Quraysh said to the Jews, "Give us something we can ask this man about."They replied, "Ask him about the spirit."So they asked him, and then came the revelation, "They ask you about the spirit. Say, the spirit is from the affair of my Lord, and you have been given only a little knowledge" [Isra 17:85].They said, "We have been given much knowledge. We have been given the Torah, and whoever is given the Torah has been given a great deal of good."So Allah revealed "Say, if the sea were ink for the words of my Lord, the sea would run dry" [Kahf 18:109].
حدثنا قتيبة بن سعيد حدثنا يحيى بن زكريا عن داود عن عكرمة
قالت قريش لليهود أعطونا شيئا نسأل عنه هذا الرجل فقالوا سلوه عن الروح فسألوه فنزلت {ويسألونك عن الروح قل الروح من أمر ربي وما أوتيتم من العلم إلا قليلا} قالوا أوتينا علما كثيرا أوتينا التوراة ومن أوتي التوراة فقد أوتي خيرا كثيرا قال فأنزل الله عز وجل {قل لو كان البحر مدادا لكلمات ربي لنفد البحر}
Its isnad is sahih. Dawud is Ibn Abu Hind. The hadith was narrated by Tirmidhi 4:137-138 from Qutayba, who said, "A hasan gharib hadith from this route." His commentator quoted from Hafiz that he said in Fath al-Bari, "Its narrators are the narrators of Muslim." Ibn Kathir quoted it in his Tafsir 5:227 from this same place. Suyuti mentioned it in Durr Manthur 4:199-200 and also attributed it to Nasai, Ibn Munzir, Ibn Hibban, and Abu Shaykh in Azamah, and to Hakim, who graded it sahih, and to Ibn Mardawayh, and to Abu Naeem and Bayhaqi, both in Dalail.
