Sahih (Sahih al-Bukhari)
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}
