What is the ruling on naming a Quranic Surah "minor Surah" and what is the correct expression that should be used?

Scholars have differed on the permissibility of the phrase "short surah." Some have permitted it, citing the statement of Ibn ʿUmar: "And what part of the Qur’an is not from the Mufassal (detailed)? Rather, say 'short surahs' or 'small surahs.'" Others, like Ibn Sīrīn and Abu al-ʿĀliyah, disliked it due to Allah's saying: "Indeed, We will cast upon you a heavy word" (Quran 73:5). Therefore, it is possible to say: "a light surah" (surah yasīrah). There is no harm in the opinion that it is not disliked.
