All of the Qur’an is good, but some parts are more special that others

Praise
be to Allah

Allah, may He be
glorified, sent down the Qur’an to His Prophet, and made its soorahs 114 in
number. Some of these soorahs are more special than others, as there are
saheeh hadiths which highlight the special virtue of Soorat al-Faatihah, al-Ikhlaas,
Soorat al-Kaafiroon, the Mi‘wadhatayn [al-Falaq and an-Naas], az-Zalzalah,
al-A‘laa, Soorat al-Baqarah and Aal ‘Imraan. As for the rest of soorahs of
the Qur’an, they have their own special virtues too.

The soorahs are
given names, because each one discusses a particular topic which makes it
stand out from other soorahs, and contains rulings, exhortation and
etiquette, and it has a particular significance in that the one who recites
it will have a reward according to what the soorah contains of exhortation
and rulings that are unique to it.

And Allah knows
best.
