The Book of the Believer · Hadith 172 (#Ḥadīth #2)
Chapter 8 | What Allah (azwj) has Forbidden a Believer to do Against a Fellow Believer
172 - وعن أبي عبد الله عليه السلام قال: من بهت مؤمنا أو مؤمنة بما ليس فيه، بعثه الله عز وجل في طينة خبال، حتى يخرج مما قال قلت: وما طينة الخبال؟ قال: صديد يخرج من فروج المومسات.
172. It has been reported that Abu 'Abd Allah said: One who accuses a believing man or believing woman falsely will be raised on the Day of Judgment by Allah in a messy substance unless he unsays it. The reporter asked, 'What is this messy substance?' It is pus flowing from the genitals of the unchaste women,' the Imam replied.
