Narrated `Imran:

The Prophet (ﷺ) said, "I looked into paradise and saw that the majority of its people were the poor, and I looked into the Fire and found that the majority of its people were women."

حَدَّثَنَا عُثْمَانُ بْنُ الْهَيْثَمِ، حَدَّثَنَا عَوْفٌ، عَنْ أَبِي رَجَاءٍ، عَنْ عِمْرَانَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ اطَّلَعْتُ فِي الْجَنَّةِ فَرَأَيْتُ أَكْثَرَ أَهْلِهَا الْفُقَرَاءَ وَاطَّلَعْتُ فِي النَّارِ فَرَأَيْتُ أَكْثَرَ أَهْلِهَا النِّسَاءَ ‏"‏‏.‏
