Narrated Yusuf bin Mahik:
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}
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."
