باب مَا جَاءَ فِي صِفَةِ الْجَنَّةِ وَأَنَّهَا مَخْلُوقَةٌ
Sahih al-Bukhari 3241

Narrated `Imran bin Husain:

The Prophet (ﷺ) said, "I looked at Paradise and found poor people forming the majority of its inhabitants; and I looked at Hell and saw that the majority of its inhabitants were women."

حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا سَلْمُ بْنُ زَرِيرٍ، حَدَّثَنَا أَبُو رَجَاءٍ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ اطَّلَعْتُ فِي الْجَنَّةِ فَرَأَيْتُ أَكْثَرَ أَهْلِهَا الْفُقَرَاءَ، وَاطَّلَعْتُ فِي النَّارِ فَرَأَيْتُ أَكْثَرَ أَهْلِهَا النِّسَاءَ ‏"‏‏.‏
