A Surah (
The word sura was used at the time of Muhammad as a term with the meaning of a chapter or a portion of the Quran. This is evidenced by the appearance of the word sura in multiple locations in the Quran such as verse 24:1: "A sura that We have sent down and appointed, and We have sent down in it signs, clear signs, that haply you will remember." Its plural form suwar is also mentioned in the Quran: "Or do they say, He invented it? Say, "Then bring ten suwar like it and call upon whomever you can besides God, if you are truthful."
