Surahs in the Quran are arranged neither chronologically nor thematically. Instead, they follow a divinely inspired order. The Quran begins with Surah Al-Fatihah (The Opening) and progresses with longer chapters likeĀ Surah Al-Baqarah, placed early, while shorter chapters, such as Surah Al-Kawthar, appear later.
This arrangement was finalized during the time of Prophet Muhammad (peace be upon him) and preserved by his companions under divine guidance.
