Sahih al-Bukhari 4817
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
The Statement of Allah the Most High: "And that thought of yours which you thought about your Lord, has brought you to destruction, and you have become (this Day) of those utterly lost!" (V.41:23)
Narrated `Abdullah: There gathered near the House (i.e. the Ka`ba) two Quraishi persons and a person from Thaqif (or two persons from Thaqif and one from Quraish), and all of them with very fat bellies but very little intelligence. One of them said, "Do you think that Allah hears what we say?" Another said, "He hears us when we talk in a loud voice, but He doesn't hear us when we talk in a low tone." The third said, "If He can hear when we talk in a loud tone, then He can also hear when we speak in a low tone." Then Allah, the Honorable, the Majestic revealed: 'And you have not been screening against yourself lest your ears, and eyes and your skins should testify against you....' (41:22-23) This hadith has been narrated through another chain as well.
