حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ دَاوُدَ، عَنِ الشَّعْبِيِّ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، قَالَتْ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنْ قَوْلِهِ عَزَّ وَجَلَّ { يَوْمَ تُبَدَّلُ الأَرْضُ غَيْرَ الأَرْضِ وَالسَّمَوَاتُ} فَأَيْنَ يَكُونُ النَّاسُ يَوْمَئِذٍ يَا رَسُولَ اللَّهِ فَقَالَ " عَلَى الصِّرَاطِ " .
