Qaf 50:5

<h2>Which was revealed in Makkah</h2><h2>The Beginning of the Mufassal Section of the Qur'an</h2><p>This Surah is the first Surah in the Mufassal section of the Qur'an, according to the correct view.

The nine next Surahs are, Subhan (or Al-Isra' (17), Al-Kahf (18), Maryam (19), Ta Ha (20), Al-Anbiya' (21), Al-Hajj (22), Al-Mu`minun (23), …
