باب مَا يَكُونُ مِنَ الظَّنِّ
Sahih al-Bukhari 6068

Narrated Al-Laith:

`Aisha said "The Prophet (ﷺ) entered upon me one day and said, 'O `Aisha! I do not think that so-and-so and so-and-so know anything of our religion which we follow."'

حَدَّثَنَا ابْنُ بُكَيْرٍ، حَدَّثَنَا اللَّيْثُ، بِهَذَا وَقَالَتْ دَخَلَ عَلَىَّ النَّبِيُّ صلى الله عليه وسلم يَوْمًا وَقَالَ ‏ "‏ يَا عَائِشَةُ مَا أَظُنُّ فُلاَنًا وَفُلاَنًا يَعْرِفَانِ دِينَنَا الَّذِي نَحْنُ عَلَيْهِ ‏"‏‏.‏
