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)
رَأَيْتُ النَّبِيَّ ﷺ «يَسْتُرُنِي بِرِدَائِهِ وَأَنَا أَنْظُرُ إِلَى الْحَبَشَةِ يَلْعَبُونَ فِي الْمَسْجِدِ حَتَّى أَكُونَ أَنَا أَسْأَمُ فَاقْدُرُوا قَدْرَ الْجَارِيَةِ الْحَدِيثَةِ السِّنِّ الْحَرِيصَةِ عَلَى اللهْوِ»
