Riyad as-Salihin 1532
'Aishah (May Allah be pleased with her) said:
The Messenger of Allah (ﷺ) said, "I do not think that so-and-so understands anything of our Faith." [Al-Bukhari] Al-Bukhari said: Al- Laith bin Sa'd, who is one of the narrators of this Hadith, said: The two men mentioned by the Prophet (ﷺ) in this Hadith were hypocrites (i.e., they revealed Faith and concealed disbelief).
