118. At the end of the historical account, the same theme, with which the Surah began, is resumed. For reference, see (verses 1-9).
119. That is, this lucid Book whose verses are being recited to you, and this admonition from which the people are turning away, is not the product of the whims of a man. It has not been written and compiled by Muhammad (peace be upon him) himself, but it consists of the revelations of the Lord of this universe.
120. That is, Angel Gabriel, as mentioned in (Surah Al- Baqarah, Ayat 97): Say to them: Whosoever is the enemy to Gabriel, he should understand that he has, by Allah’s command, revealed to your heart the Quran. Here the object of using the title of the trustworthy Spirit for Gabriel implies that the Quran is not being sent down by Allah through some material agency, which is subject to change and vacillation; but through a pure Spirit, having no tinge of materialism, and who is perfectly trustworthy. This Spirit conveys the messages of Allah precisely in the same form and with the same content as they are entrusted to him. It is not possible for him to tamper with the messages, or to make his own additions to them in any way.
121. This sentence may be related to “the trustworthy Spirit has come down” and also to: “who are (appointed by God) to warn.” In the first case, it will mean that the trustworthy Spirit has brought it down in plain Arabic language, and in the second case, it will mean that the Prophet (peace be upon him) is included among those Prophets who were appointed to warn the people in the Arabic language, i.e. Houd, Salih, Ishmael and Shuaib (peace be upon them all). In both cases the object is the same: the divine message has not been sent down in a dead or mysterious language, or in a language of riddles and enigmas, but in such clear and lucid Arabic, which can be understood easily by every Arab and every non Arab who has learned Arabic. As such, the people who are turning away from it, they cannot have the excuse that they could not understand the message of the Quran. The only reason of their denial and aversion is that they are afflicted with the same disease with which Pharaoh, the people of Abraham the people of Noah, the people of Lot, the Aad and the Thamud, and the people of Aiykah were afflicted.
