'Urwa reported:'Aisha said to me: Your fathers (Zubair and Abu Bakr) were amongst those about whom (it has been revealed):" Those who responded to the call of Allah and His Messenger after the misfortune had fallen upon them."
حَدَّثَنَا أَبُو كُرَيْبٍ، مُحَمَّدُ بْنُ الْعَلاَءِ حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا إِسْمَاعِيلُ، عَنِ الْبَهِيِّ، عَنْ عُرْوَةَ، قَالَ قَالَتْ لِي عَائِشَةُ كَانَ أَبَوَاكَ مِنَ الَّذِينَ اسْتَجَابُوا لِلَّهِ وَالرَّسُولِ مِنْ بَعْدِ مَا أَصَابَهُمُ الْقَرْحُ .
