'A'isha reported:I asked Allah's Messenger (ﷺ) about the words of Allah, the Exalted and Glorious:" The day when the earth would be changed for another earth and Heaven would be changed for another Heaven (XiV. 48), (and inquired: ) (Allah's Messenger), where would the people be on that day? He said: They would be on the Sirat.
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 " .
