Summary towards detail,

likewise the story of Jesus - peace be upon him - came summarized in Surah Maryam in His statement, the Most High:

{And that We may make him a sign for the people and a mercy from Us and it was a matter decreed}

And it came detailed in Surah Ali Imran in the statement - the Most High -:

{And a messenger to the Children of Israel, that I have come to you with a sign from your Lord}

So indeed the detailed glad tidings came in this verse,

and in that verse the summarized glad tidings,

and from here the weak servant deduced that the meaning of the verse and its estimation:

"And a messenger to the Children of Israel informing that I have come to you".

And this is included in the realm of glad tidings,

and it is not related to an omitted word as Al-Suyuti indicated where he said:

"So when Allah sent him He said: Indeed I am the messenger of Allah to you by that I have come to you" and Allah knows best.

[Explanation of the rare words of the Quran:]

From the matters which tafsir by transmission includes is the explanation of the rare words of the Quran as well,

and its foundation is upon tracing the language of the Arabs or upon understanding the context of the verse and knowing the suitability of the word to the parts of the sentence in which it occurred there.

The entry point of ijtihad in explaining the word:

And here for the intellect is an entry point and for disagreement is a scope,

since the single word comes in the language of the Arabs for various meanings,

and the minds and perceptions differ in tracing the usages of the Arabs,

and paying attention to the preceding and the succeeding.

And therefore the statements of the Companions and the Successors - may Allah be pleased with them - differed in this chapter -

and each of them traversed an opinion and a school.
