On the Night of Mi'raj, I saw people lying on their backs with drum-like, transparent bellies where there are all kinds of creatures. I asked my brother Jibrail, "What are they?" He replied, "O the Messenger of Allah, they are from your Ummah [community, nation]." I asked again, "What is their guilt?" He answered, "They are those who accumulated wealth without differentiating between lawful and unlawful means and who did not think whether the money they earned was lawful or unlawful. The unlawful substances they consumed turned to this state in their bodies."
This hadith can be found on My Religion Islam.
Is this a sahih hadith?
