Question : What is the ruling on reciting the Surahs against the order of the Qur’an in prayer?
Answer : According to the Hanafi School, reciting the Surahs in the order that they are in the Qur’an is necessary (wajib) inside the Fardh and Wajib prayers such as the five daily obligatory prayers, the Jumu’ah prayer, the Witr prayer and the Eid prayer. As such, reciting the Surahs in a reversed order deliberately is considered to be prohibitively disliked (makruh tahriman) in these prayers, although it is not disliked in voluntary (nafl) prayers.
And Allah knows best
