English Translation of Hadith
Hazrat Aisha (May Allah be pleased with her) said: The Messenger of Allah [SAWW](PBUH) said, "I do not think that so-and-so understands anything of our Faith.”
[Al-Bukhari Book 08, Chapter 73, Hadith # 93]
Al-Bukhari said: Hazrat Al-Laith bin Saad (May Allah be pleased with him), who is one of the narrators of this Hadith, said: The two men mentioned by the Prophet [SAWW](PBUH) in this Hadith were hypocrites (i.e., they revealed Faith and concealed disbelief).
Lesson : as mentioned above in Surah Al-Qasas Ayat 49. “bring a Book from Allah, which is a better guide than these two” Hypocrites are also people of mischievous and doubtful conduct. It is, therefore, not only permissible but necessary to make people aware of their real position so that people become cautious about them and their religious and worldly life may remain safe from their machinations.
