What did Allah (swt) reveal when two people from Quraish and their brother-in-law from Thaqif were discussing whether He (swt) hears their conversation? (Peace be upon him)
 Narrated Ibn Mas`ud:                     (regarding) the Verse: 'And you have not been screening against yourself lest your ears, and your eyes and your skins should testify against you..' (41.22) While two persons from Quraish and their brotherin- law from Thaqif (or two persons from Thaqif and their brother-in-law from Quraish) were in a house, they said to each other, "Do you think that Allah hears our talks?" Some said, "He hears a portion thereof" Others said, "If He can hear a portion of it, He can hear all of it." Then the following Verse was revealed: 'And you have not been screening against yourself lest your ears, and your eyes and your skins should testify against you...' (41.22)
