Messenger of Allah ﷺ said to me, "Were your people not close to the Pre-Islamic period of ignorance, I would have demolished the Kaʿba and would have rebuilt it on its original foundations laid by Abraham (for Quraish had curtailed its building), and I would have built a back door (too)."  

لِي رَسُولُ اللَّهِ ﷺ لَوْلاَ حَدَاثَةُ قَوْمِكِ بِالْكُفْرِ لَنَقَضْتُ الْبَيْتَ ثُمَّ لَبَنَيْتُهُ عَلَى أَسَاسِ إِبْرَاهِيمَ عَلَيْهِ السَّلاَمُ فَإِنَّ قُرَيْشًا اسْتَقْصَرَتْ بِنَاءَهُ وَجَعَلْتُ لَهُ خَلْفًا قَالَ أَبُو مُعَاوِيَةَ حَدَّثَنَا هِشَامٌ خَلْفًا يَعْنِي بَابًا  

Messenger of Allah may peace be upon him) said to me: Had your people not been unbelievers in the recent past (had they not quite recently accepted Islam), I would have demolished the Ka'ba and would have rebuilt it on the foundation (laid) by Ibrahim; for when the Quraish had built the Ka'ba, they reduced its (area), and I would also have built (a door) in the rear.  

لِي رَسُولُ اللَّهِ ﷺ لَوْلاَ حَدَاثَةُ عَهْدِ قَوْمِكِ بِالْكُفْرِ لَنَقَضْتُ الْكَعْبَةَ وَلَجَعَلْتُهَا عَلَى أَسَاسِ إِبْرَاهِيمَ فَإِنَّ قُرَيْشًا حِينَ بَنَتِ الْبَيْتَ اسْتَقْصَرَتْ وَلَجَعَلْتُ لَهَا خَلْفًا  

"The Messenger of Allah said: "Were it not for the fact that your people have recently left disbelief, I would have knocked down the House and rebuilt it on the foundation of Ibrahim, peace be upon him, and I would have given it a back door. For when the Quraish built the House, they made it too small.'"  

قَالَ رَسُولُ اللَّهِ ﷺ لَوْلاَ حَدَاثَةُ عَهْدِ قَوْمِكِ بِالْكُفْرِ لَنَقَضْتُ الْبَيْتَ فَبَنَيْتُهُ عَلَى أَسَاسِ إِبْرَاهِيمَ عَلَيْهِ السَّلاَمُ وَجَعَلْتُ لَهُ خَلْفًا فَإِنَّ قُرَيْشًا لَمَّا بَنَتِ الْبَيْتَ اسْتَقْصَرَتْ  

"The Messenger of Allah said: "Were it not for the fact that your people have recently left disbelief, I would have knocked down the House and rebuilt it on the foundation of Ibrahim, peace be upon him, and I would have given it a back door. For when the Quraish built the House, they made it too small.'" (Using translation from Nasāʾī 2901)   

قَالَ رَسُولُ اللهِ ﷺ لَوْلَا حَدَاثَةُ عَهْدِ قَوْمِكِ بِالْكُفْرِ لَنَقَضْتُ الْكَعْبَةَ ثُمَّ جَعَلْتُهَا عَلَى أُسِّ إِبْرَاهِيمَ عَلَيْهِ السَّلَامُ فَإِنَّ قُرَيْشًا يَوْمَ بَنَتْهَا اسْتَقْصَرَتْ وَلَجَعَلْتُ لَهَا خَلْفًا قَالَ أَبُو أُسَامَةَ خِلْفًا

لِي رَسُولُ اللَّهِ ﷺ «لَوْلَا حَدَاثَةُ عَهْدِ قَوْمِكِ بِالْكُفْرِ لَنَقَضْتُ الْكَعْبَةَ ثُمَّ لَبَنَيْتُهَا عَلَى أُسِّ إِبْرَاهِيمَ فَإِنَّ قُرَيْشًا حِينَ بَنَتْ اسْتَقْصَرَتْ ثُمَّ جَعَلَتْ لَهَا خَلْفًا»  

"لَوْلا حَدَاثَةُ عَهْدِ قَوْمك بِالكفْرِ لَنَقَضْتُ البَيتَ فَبَنَيتُهُ عَلَى أسَاس إبْرَاهِيمَ وَجَعَلتُ لَهُ خَلفًا، فَإِنَّ قُرَيشًا لَمَّا بَنَتِ البيت اسْتَقْصَرَتْ".
