حَدَّثَنِي يَحْيَى، حَدَّثَنَا وَكِيعٌ، عَنْ نَافِعِ بْنِ عُمَرَ، عَنِ ابْنِ أَبِي مُلَيْكَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ كَانَتْ تَقْرَأُ ‏{‏إِذْ تَلِقُونَهُ بِأَلْسِنَتِكُمْ‏}‏ وَتَقُولُ الْوَلْقُ الْكَذِبُ‏.‏ قَالَ ابْنُ أَبِي مُلَيْكَةَ وَكَانَتْ أَعْلَمَ مِنْ غَيْرِهَا بِذَلِكَ لأَنَّهُ نَزَلَ فِيهَا‏.‏
