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.
