The Messenger of Allah ﷺ said, "I looked into Paradise and saw that most of its people were the poor, and I looked into the Fire and saw that most of its people were women."
حدثنا وكيع حدثنا حماد بن نجيح سمعه من أبي رجاء
قال رسول الله ﷺ اطلعت في الجنة فرأيت أكثر أهلها الفقراء واطلعت في النار فرأيت أكثر أهلها النساء
