Jami` at-Tirmidhi 875 
Al-Aswad bin Yazid narrated that:
Ibn Az-Zubair said to him: "Narrated to me from what the Mother of the Believers used to (secretly) inform you about" - meaning Aishah - so he said: "She narrated to me that the Messenger of Allah said: 'Had your people not been still close to the pre-Islamic period of ignorance, then I would demolish the Ka'bah and rebuild it with two doors.'" He said: "So when Ibn Az-Zubair came to power he demolished it and rebuilt it with two doors."
حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا أَبُو دَاوُدَ، عَنْ شُعْبَةَ، عَنْ أَبِي إِسْحَاقَ، عَنِ الأَسْوَدِ بْنِ يَزِيدَ، أَنَّ ابْنَ الزُّبَيْرِ، قَالَ لَهُ حَدِّثْنِي بِمَا، كَانَتْ تُفْضِي إِلَيْكَ أُمُّ الْمُؤْمِنِينَ يَعْنِي عَائِشَةَ فَقَالَ حَدَّثَتْنِي أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ لَهَا ‏ "‏ لَوْلاَ أَنَّ قَوْمَكِ حَدِيثُو عَهْدٍ بِالْجَاهِلِيَّةِ لَهَدَمْتُ الْكَعْبَةَ وَجَعَلْتُ لَهَا بَابَيْنِ ‏"‏ ‏.‏ قَالَ فَلَمَّا مَلَكَ ابْنُ الزُّبَيْرِ هَدَمَهَا وَجَعَلَ لَهَا بَابَيْنِ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
