Tafseer By Ibn Kathir Of The Quran (3:14)
Ibn kathir does not attribute this hadith to the prophet. His words are: كما وردت الأحاديث بالترغيب في التزويج والاستكثار منه، وإن خير هذه الأمة من كان أكثرها نساء، It means it has been narrated in Hadith literature, and hadith literature may include sayings of the companions which are not explicitly attributed to the Prophet. The narration of Bukhari makes it clear that it is the saying of Ibn Abbas.
