Some of its inhabitants
Usamah (radiAllahu anhu) narrated that the Prophet (salAllahu alayhi wasalam) stated: "I stood at the gate of Paradise and saw that the majority of the people who entered it were the poor, while those of means were held [for account], except the companions of the Fire, who were already ordered to [be taken to] the Fire. And I stood at the gate of the Fire and [saw that] the majority of those who entered it were women."
[Sahih al-Bukhari and Muslim]
Ibn Abbas (radiAllahu anhu) stated: "The Prophet (salAllahu alayhi wasalam) said, 'I looked into the Hellfire, and the majority of its dwellers were women who were ungrateful.' It was asked, 'Did they disbelieve in (i.e. were ungrateful to ] Allah?' He replied, 'They were ungrateful to their husbands and were ungrateful for favors and the good deeds done for them. If you had always been good to one of them and then she saw something in you not to her liking, she would say, 'I have never seen any good from you at all."'"
"And We sent Musa with Our clear [signs] and an authority manifest unto Pharaoh and his chiefs, but they followed the command of Pharaoh. And the command of Pharaoh was no right guide. He will go before his people on the Day of Judgment and lead them into the Fire. And how evil will be the place to which they are led. And they are followed by a curse in this [life] and on the Day of Judgment. And evil is the gift which will be given [to them]."
[Hud, 11: 96-99]
"The Fire - they will be exposed to it morning and evening, and on the Day that judgment will be established [it will be said], 'Cast the people of Pharaoh into the severest punishment.'"
[Ghafir, 40: 46]
The Wives of Nuh and Lut:
"Allah has given an example of those who disbelieve: the wife of Nuh and the wife of Lut. They were under two of Our righteous servants but betrayed them; so they [the two prophets] did not benefit them [the wives] before Allah at all, and they were told, 'Enter the Fire with those who enter.'"
[at-Tahreem, 66: 10]
Abu Lahab and His Wife:
"May the hands of Abu Lahab be ruined, and ruined is he. His wealth will not avail him nor that which he gained. He will enter a flaming fire and his wife [as well] - the carrier of firewood - around her neck a rope of palm fiber."
[Masad, 111: 1-5]
Amr bin Luhayy:
Abu Hurairah (radiAllahu anhu) reported that Allah's Messenger (salAllahu alayhi wasalam) said: "I saw 'Amr bin Luhayy bin Qam'a bin Khindif, brother of Bani Ka'b, dragging his intestines in the Fire."
Amr bin Amir al-Khuya'i:
Abu Hurairah (radiAllahu anhu) stated that Allah's Messenger (salAllahu alayhi wasalam) said: "I saw 'Amr bin 'Amir al-Khuya'i dragging his intestines in the Fire; he was the first who dedicated to animals to false deities."
Ibn Abbas (radiAllahu anhu) reported that the Messenger of Allah (salAllahu alayhi wasalam) said: "Of the inmates of the Fire, the one with the easiest punishment will be Abu Talib; he will be wearing a pair of shoes which will cause his brain to boil."
"He will say, 'Enter into the company of communities who passed away before you - of jinn and men - into the Fire.'"
[al-A'raf, 7: 38]
"If your Lord had so willed, He could have make mankind one people, but they will not cease to dispute except those on whom your Lord has bestowed His mercy. And the word of your Lord will be fulfilled: 'Certainly I will fill Hell with jinn and men all together.'"
[Hud, 11: 118-119]
"Then they will be thrown into it [the Hellfire] on their faces - they and those straying in evil and the soldiers of Iblees, all together."
[ash-Shu'ara, 26: 94-95]
