"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.'" (Using translation from Ibn Mājah 188)
الْحَمْدُ لِلَّهِ الَّذِي وَسِعَ سَمْعُهُ الْأَصْوَاتَ لَقَدْ جَاءَتِ الْمُجَادِلَةُ إِلَى النَّبِيِّ ﷺ تُكَلِّمُهُ وَأَنَا فِي نَاحِيَةِ الْبَيْتِ مَا أَسْمَعُ مَا تَقُولُ فَأَنْزَلَ اللهُ ﷻ {قَدْ سَمِعَ اللهُ قَوْلَ الَّتِي تُجَادِلُكَ فِي زَوْجِهَا } [المجادلة 1] إِلَى آخِرِ الْآيَةِ
