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. (Using translation from Bukhārī 5236)
عَائِشَةُ رَأَيْتُ رَسُولَ اللهِ ﷺ يَسْتُرُنِي بِرِدَائِهِ وَأَنَا أَنْظُرُ إِلَى الْحَبَشَةِ وَهُمْ يَلْعَبُونَ وَأَنَا جَارِيَةٌ فِي الْمَسْجِدِ فَاقْدُرُوا قَدْرَ الْجَارِيَةِ الْحَدِيثَةِ السِّنِّ
