Specific People Who Will Be In Hell
The kuffaar and mushikreen will be in Hell, no doubt about it, but the Qur'an and hadith also mention specific people who will be in the Fire. One of them is the Pharaoh who ruled at the time of Musa (as):
"He [Pharaoh] will go before his people on the Day of Judgement, and will lead them into the Fire.." (11:98)

Also included are the wives of Nuh (as) and Lut (as):

"Allah sets forth for an example to the unbelievers, the wife of Nuh and the wife of Lut. They were [respectively] under two of Our righteous slaves, but they were false to their [husbands] and they profited nothing before Allah on their account, but were told: "Enter the Fire, along with those who enter!" (66:10)

Abu Lahab and his wife are also among those mentioned specifically:

"Perish the hands of the Father of Flame [Abu Lahab]! Perish he! No profit to him from all his wealth and all his gains! Burnt soon will he be in a Fire of blazing flames! His wife shall carry the [crackling] wood, as fuel! A twisted rope of palm fibre round her [own] neck!" (111:1-5)

Another of them is 'Amr ibn 'Aamir al-Khuzaa'i, whom the Prophet (saw) being disembowelled in Hell (sahih hadith narrated by al-Bukhaari, Muslim, Ahmad); and the one who killed 'Ammar and plundered his possessions. A report with a Saheeh isnaad quoted in Mu'jam at-Tabaraani from 'Amr ibn al-'Aas, and his son states that the Prophet (saw) said, "The one who killed 'Ammaar and plundered his possessions will be in Hell". (Saheeh al-Jaami', 4/110, #4170)
