[Those are the worst of creatures], meaning: the creation.
Muhammad said: Most recitations of (al-bariyya) are without a hamza due to frequent usage and the derivation of the term from: Allah created (bara'a) the creation [and brought it into existence].
Yahya: From Hammad, from Abu al-Muhazzam, from Abu Hurayra who said: "The believer is more noble to Allah than the angels who are with Him."
