Sunan Ibn Majah 188
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.'"
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، حَدَّثَنَا الأَعْمَشُ، عَنْ تَمِيمِ بْنِ سَلَمَةَ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنْ عَائِشَةَ، قَالَتِ الْحَمْدُ لِلَّهِ الَّذِي وَسِعَ سَمْعُهُ الأَصْوَاتَ، لَقَدْ جَاءَتِ الْمُجَادِلَةُ إِلَى النَّبِيِّ ـ صلى الله عليه وسلم ـ وَأَنَا فِي نَاحِيَةِ الْبَيْتِ تَشْكُو زَوْجَهَا وَمَا أَسْمَعُ مَا تَقُولُ فَأَنْزَلَ اللَّهُ ‏{قَدْ سَمِعَ اللَّهُ قَوْلَ الَّتِي تُجَادِلُكَ فِي زَوْجِهَا}‏ ‏.‏
