Narrated Abu Huraira:
حَدَّثَنَا آدَمُ ، حَدَّثَنَا شُعْبَةُ ، حَدَّثَنَا مُحَمَّدُ بْنُ زِيَادٍ ، قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ ، يَقُولُ قَالَ النَّبِيُّ ـ أَوْ قَالَ أَبُو الْقَاسِمِ ـ صلى الله عليه وسلم " بَيْنَمَا رَجُلٌ يَمْشِي فِي حُلَّةٍ، تُعْجِبُهُ نَفْسُهُ مُرَجِّلٌ جُمَّتَهُ، إِذْ خَسَفَ اللَّهُ بِهِ، فَهْوَ يَتَجَلَّلُ إِلَى يَوْمِ الْقِيَامَةِ " .
The Prophet (or 'Abul Qasim) said, "While a man was walking, clad in a two-piece garment and proud of himself with his hair well-combed, suddenly Allah made him sink into the earth and he will go on sinking into it till the Day of Resurrection.
