Sahih al-Bukhari 67:169
Narrated `Aisha:
The Prophet (ﷺ) was screening me with his Rida' (garment covering the upper part of the body) while I was looking at the Ethiopians who were playing in the courtyard of the mosque. (I continued watching) till I was satisfied. So you may deduce from this event how a little girl (who has not reached the age of puberty) who is eager to enjoy amusement should be treated in this respect.

حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ الْحَنْظَلِيُّ، عَنْ عِيسَى، عَنِ الأَوْزَاعِيِّ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم يَسْتُرُنِي بِرِدَائِهِ، وَأَنَا أَنْظُرُ إِلَى الْحَبَشَةِ يَلْعَبُونَ فِي الْمَسْجِدِ، حَتَّى أَكُونَ أَنَا الَّذِي أَسْأَمُ، فَاقْدُرُوا قَدْرَ الْجَارِيَةِ الْحَدِيثَةِ السِّنِّ الْحَرِيصَةِ عَلَى اللَّهْوِ.
