This hadith has been narrated on the authority of 'Abdullah b. Rufai, with the same chain of transmitters (but with the addition of these words):
حَدَّثَنَاهُ أَحْمَدُ بْنُ يُونُسَ ، حَدَّثَنَا زُهَيْرٌ ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ رُفَيْعٍ ، بِهَذَا الإِسْنَادِ وَفِي حَدِيثِهِ قَالَ فَلَقِيتُ أَبَا جَعْفَرٍ فَقُلْتُ إِنَّهَا إِنَّمَا قَالَتْ بِبَيْدَاءَ مِنَ الأَرْضِ فَقَالَ أَبُو جَعْفَرٍ كَلاَّ وَاللَّهِ إِنَّهَا لَبَيْدَاءُ الْمَدِينَةِ .
" When I met Abu Ja'far I told him that she (simply) meant the plain ground. Thereupon Abu Ja'far said: No, by God, she meant the plain ground of Medina.
