Sahih Muslim
وَحَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا إِسْمَاعِيلُ، عَنْ قَيْسٍ، عَنْ عُقْبَةَ بْنِ عَامِرٍ، قَالَ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم " أُنْزِلَ - أَوْ أُنْزِلَتْ - عَلَىَّ آيَاتٌ لَمْ يُرَ مِثْلُهُنَّ قَطُّ الْمُعَوِّذَتَيْنِ " .
'Uqba b. 'Amir reported: The Messenger of Allah (ﷺ) said to me: There have been sent down to me verses the like of which had never been seen before. They are the Mu'awwadhatain.
