From Sahih Bukhari (Hadith 5790):
Narrated `Abdullah bin `Umar:Allah's Messenger (ﷺ) said, "While a man was dragging his Izar on the ground (behind him), suddenly Allah made him sink into the earth and he will go on sinking into it till the Day of Resurrection." Narrated Abu Huraira: that he heard the Prophet (narrating as above No)
