Good Manners and Form (Al-Adab)
78/59. Chapter:
What sort of suspicion is allowed.
Sahih Bukhari
حَدَّثَنَا سَعِيدُ بْنُ عُفَيْرٍ، حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ قَالَ النَّبِيُّ صلى الله عليه وسلم " مَا أَظُنُّ فُلاَنًا وَفُلاَنًا يَعْرِفَانِ مِنْ دِينِنَا شَيْئًا ". قَالَ اللَّيْثُ كَانَا رَجُلَيْنِ مِنَ الْمُنَافِقِينَ.
Narrated `Aisha: The Prophet (ﷺ) said, "I do not think that so-and-so and so-and-so know anything of our religion." (And Al-Laith said, "These two persons were among the hypocrites.")
