Sahih al-Bukhari 4876
Narrated Yusuf bin Mahik:
I was in the house of `Aisha, the mother of the Believers. She said, "This revelation: "Nay, but the 
Hour is their appointed time (for their full recompense); and the Hour will be more previous and most 
bitter." (54.46) was revealed to Muhammad at Mecca while I was a playfull little girl."
حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، حَدَّثَنَا هِشَامُ بْنُ يُوسُفَ، أَنَّ ابْنَ جُرَيْجٍ، أَخْبَرَهُمْ قَالَ أَخْبَرَنِي يُوسُفُ بْنُ مَاهَكَ، قَالَ إِنِّي عِنْدَ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ قَالَتْ لَقَدْ أُنْزِلَ عَلَى مُحَمَّدٍ صلى الله عليه وسلم بِمَكَّةَ، وَإِنِّي لَجَارِيَةٌ أَلْعَبُ ‏{‏بَلِ السَّاعَةُ مَوْعِدُهُمْ وَالسَّاعَةُ أَدْهَى وَأَمَرُّ‏}‏
