It was narrated that 'Aishah said:
"Praise is to Allah Whose hearing encompasses all voices. The woman who disputed concerning her husband (Al-Mujadilah) came to the Prophet when I was (sitting) in a corner of the house, and she complained about her husband, but I did not hear what she said. The Allah revealed: 'Indeed Allah has heard the statement of her that disputes with you concerning her husband.'" (JA)
