Hadith: There are two types of the dwellers of Hellfire whom I have not seen: people with whips like the tails of cows with which they beat people, and women who will be dressed yet naked, inviting to evil, and they themselves are inclined to it

عَنْ أَبِي هُرَيْرَةَ رضي الله عنه قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ:
«صِنْفَانِ مِنْ أَهْلِ النَّارِ لَمْ أَرَهُمَا، قَوْمٌ مَعَهُمْ سِيَاطٌ كَأَذْنَابِ الْبَقَرِ يَضْرِبُونَ بِهَا النَّاسَ، وَنِسَاءٌ كَاسِيَاتٌ عَارِيَاتٌ مُمِيلَاتٌ مَائِلَاتٌ، رُؤُوسُهُنَّ كَأَسْنِمَةِ الْبُخْتِ الْمَائِلَةِ، لَا يَدْخُلْنَ الْجَنَّةَ، وَلَا يَجِدْنَ رِيحَهَا، وَإِنَّ رِيحَهَا لَيُوجَدُ مِنْ مَسِيرَةِ كَذَا وَكَذَا».
[صحيح] - [رواه مسلم] - [صحيح مسلم: 2128]

Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said:
"There are two types of the dwellers of Hellfire whom I have not seen: people with whips like the tails of cows with which they beat people, and women who will be dressed yet naked, inviting to evil, and they themselves are inclined to it. Their heads will appear like the humps of the Bactrian camels, inclined to one side. They will not enter Paradise nor will they smell its fragrance; the fragrance that is smelled from such-and-such a distance."
[Authentic hadith] - [Narrated by Muslim] - [Sahih Muslim - 2128]

Explanation

The Prophet (may Allah's peace and blessings be upon him) warns against two types of people from the dwellers of Hellfire whom he did not see and who did not exist during his time; rather, they will come to exist afterwards.
First type: They are people who have whips like the long tails of cows with which they beat people, and those are the policemen and the oppressors' soldiers who beat people wrongfully.
Second type: They are women who have abandoned chastity and modesty, which usually constitute part of the woman's nature.
Their description: Dressed in reality but naked in meaning because they wear transparent clothes that reveal the color of their skin; and they cover parts of their body and expose other parts to show their beauty. They cause men's hearts to be inclined to them by their clothes and swaggering gait. They walk while inclining their shoulders and invite others to deviation and aberration that they indulge in. Moreover, their heads are like the inclined hump of a camel, as they make their heads look larger and bigger by wrapping a scarf and the like around it. Their heads are likened to the humps of the Bactrian camels given the fact that they raise their hair and braids on top of their heads and these braids are inclined to one side of the head just like the camel's hump. Women who fit such a description are subject to this severe threat of not entering Paradise, or smelling its fragrance, or even approaching it although the fragrance of Paradise could be smelled from a far distance.
