The Messenger of Allah ﷺ said, "I looked into Paradise and saw that most of its inhabitants were the poor, and I looked into the Fire and saw that most of its inhabitants were the wealthy and women."
حدثنا عبد الله بن محمد قال عبد الله بن أحمد بن حنبل وسمعته أنا من عبد الله بن محمد بن أبي شيبة حدثنا شريك عن أبي إسحق عن السائب بن مالك
قال رسول الله ﷺ اطلعت في الجنة فرأيت أكثر أهلها الفقراء واطلعت في النار فرأيت أكثر أهلها الأغنياء والنساء
Its isnad is sahih. Sharik is Ibn Abdullah the judge. Abu Ishaq is Subayi, with the sin unvoweled and the ba given a kasrah, whose name was Amr bin Abdullah. He was a well-known, reliable follower of the companions, and Bukhari gave his biography in al-Saghir (p. 148), as did Ibn Abu Hatim in al-Jarh wal-Tadil (242/1/3-243), and Ibn Saad in al-Tabaqat 6:219-220. Subayi is a name derived from Bani Subay, a clan of Hamdan.Haythami mentioned this hadith in Majma al-Zawaid 10:261, saying, "Ahmad narrated it, and its isnad is jayyid." The word "and women" was dropped from the end of the hadith in Majma al-Zawaid, which is an error by a copyist or typesetter, since it is confirmed in the manuscripts of the Musnad and in all the sources that quoted it from there. It is also found in al-Targhib wal-Tarhib 4:85, where it says, "Ahmad narrated it with a jayyid isnad." Hafiz bin Rajab quoted it in his book al-Takhwif min al-Nar (p. 157), also attributing it to the Musnad.See what came earlier in the Musnad of Ibn Abbas, numbers 2086 and 3386.
