Sahih Muslim 2662b
'A'isha, the mother of the believers, reported that a child died and I said: There is happiness for this child who is a bird from amongst the birds of Paradise. Thereupon Messenger of Allah ﷺ said: Don't you know that Allah created the Paradise and He created the Hell and He created the dwellers for this (Paradise) and the denizens for this (Hell)?
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا جَرِيرٌ، عَنِ الْعَلاَءِ بْنِ الْمُسَيَّبِ، عَنْ فُضَيْلِ بْنِ عَمْرٍو، عَنْ عَائِشَةَ بِنْتِ طَلْحَةَ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ، قَالَتْ تُوُفِّيَ صَبِيٌّ فَقُلْتُ طُوبَى لَهُ عُصْفُورٌ مِنْ عَصَافِيرِ الْجَنَّةِ فَقَالَ رَسُولُ اللَّهِ ﷺ " أَوَلاَ تَدْرِينَ أَنَّ اللَّهَ خَلَقَ الْجَنَّةَ وَخَلَقَ النَّارَ فَخَلَقَ لِهَذِهِ أَهْلاً وَلِهَذِهِ أَهْلاً " .
