History of surah The Opening

Name

The subject matter of this Surah is why it is given the name Al-Fatihah. Fatihah is what opens a topic, a book, or anything else. Al-Fatihah is thus a kind of introduction.
Period of Revelation
One of the Holy Prophet's earliest revelations was Surah Al-Fatihah. In fact, according to reliable traditions, Muhammad (Allah's peace be upon him) received the first full Surah during this time. Only a few stochastic verses that are fragments of Alaq, Muzzammil, Muddaththir, etc. were revealed prior to this.
 

Theme

Actually, Allah has taught everyone who wants to study His book to pray this Surah. This prayer should be offered to the Lord of the Universe if you sincerely want to benefit from the Quran. The reason it is at the beginning of the Quran is to teach the reader this lesson.
This preface aims to instill in the reader a strong desire to seek direction from the Lord of the Universe, who is the only one who can provide it. As a result, Al-Fatihah subtly teaches that the best course of action for a man is to ask for guidance toward the straight path, read the Quran with the mindset of a seeker looking for the truth, and acknowledge that the Lord of the Universe is the source of all knowledge. He should therefore pray to Him for direction before starting his study of the Quran.
This theme makes it obvious that the real relationship between Al-Fatihah and the Quran is not one of a book's introduction but rather one of a prayer and its fulfillment. Al-Fatihah is the servant's prayer, and the Quran is the master's response to that prayer. In response to the servant's request for guidance, the Master spreads out the entirety of the Quran in front of him as if to say, "This is the Guidance you begged from Me."
