The Book of Commentary on the Qur'an
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا أَبُو مُعَاوِيَةَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، قَالَ قَالَتْ لِي عَائِشَةُ يَا ابْنَ أُخْتِي أُمِرُوا أَنْ يَسْتَغْفِرُوا، لأَصْحَابِ النَّبِيِّ صلى الله عليه وسلم فَسَبُّوهُمْ .Urwa reported on the authority of his father that 'A'isha said to him:O, the son of my sister, the Muslims were commanded to seek forgiveness for the Companions of Allah's Apostle (ﷺ) but they reviled them
From Sahih Muslim, whose reports the scholars accept as authentic.
