Is it permissible to recite the Surahs (Qur'anic chapters) in an order other than that of the Mus-haf (copy of the Qur’an), for example, Surah Al-Falaq before Surah Al-Nas
or something like that?
It is better to recite the Surahs in the order of the ‘Uthmany script of the Mus-haf starting with Al-Fatihah, then Al-Baqarah, then ‘Al-‘Imran, and ending with Surah Al-Nas. Accordingly, reciting Surah Al-Falaq before Surah Al-Nas is in agreement with the order of the ‘Uthmany script of the Mus-haf, not the contrary. However, reciting Surah Al-Nas, Surah Al-Falaq, and then Surah Al-Ikhlas for learning purposes is unobjectionable.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
