سورة الانسان

Imam Kazim (peace be upon him): Muhammad ibn Fudayl said: I said to Imam Kazim (peace be upon him): "What is meant by this verse: إِنَّا نَحْنُ نَزَّلْنَا عَلَیْکَ الْقُرْآنَ تَنزِیلًا [Surely We Ourselves have revealed the Quran to you revealing it in portions]?" He said: "We revealed it with the wilayah of Ali (peace be upon him)." I said: "Is it revealed in this way?" He said: "No, rather the ta'wil (interpretation) of the verse is this way."

Imam Kazim (peace be upon him): إِنَّا نَحْنُ نَزَّلْنا عَلَیْکَ الْقُرْآنَ تَنْزِیلًا [Surely We Ourselves have revealed the Quran to you revealing it in portions] [means] with the wilayah of Ali (peace be upon him).

Ibn Abbas (may Allah have mercy on him): The meaning of the verse is that We revealed the Quran, at the time of its revelation, verse by verse separately, and it was not sent down all at once.
