The provided information only mentions Surah Al-Ala (الأعلى). It doesn't explicitly state it's the "most loved." Therefore, without further context or referencing authoritative Islamic sources, it's impossible to definitively answer which Surah is the "most loved." The feeling of "most loved" is subjective and varies amongst individuals and communities.
It is crucial to consult authentic Islamic texts and scholarly opinions for accurate information regarding religious topics.
