Narrated Abu Wail:

`Ammar stood on the pulpit at Kufa and mentioned `Aisha and her coming (to Busra) and said, "She is the wife of your Prophet (ﷺ) in this world and in the Hereafter, but you people are being put to test in this issue."

حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا ابْنُ أَبِي غَنِيَّةَ، عَنِ الْحَكَمِ، عَنْ أَبِي وَائِلٍ، قَامَ عَمَّارٌ عَلَى مِنْبَرِ الْكُوفَةِ، فَذَكَرَ عَائِشَةَ وَذَكَرَ مَسِيرَهَا وَقَالَ إِنَّهَا زَوْجَةُ نَبِيِّكُمْ صلى الله عليه وسلم فِي الدُّنْيَا وَالآخِرَةِ، وَلَكِنَّهَا مِمَّا ابْتُلِيتُمْ‏.‏
