Most of Those Who Enter Hell Will be Women
Most of the sinners amongst the monotheists who enter Hell will be women, as is reported in as-Saheehayn, via Ibn 'Abbaas: in the khutbah given during a solar eclipse, the Prophet (saw) said, "I saw Hell and I saw that most of its inhabitants were women".
al-Bukhaari and Muslim report from Abu Sa'eed al-Khudri that the Prophet (saw) said, "O women give in charity, for I have seen that you form the majority of the people of Hell." They asked, "Why is that so, O Messenger of Allah (saw)?" He said, "Because you curse too much and are ungrateful for good treatment".

al-Bukhaari and Muslim report from Usaamah ibn Zayd that the Prophet (saw) said "I stood at the gate of Hell, and saw that most of those who entered were women".

Muslim reports from 'Imraan ibn Husayn (ra) that the Prophet (saw) said, "Few of the inhabitants of paradise are women".

This does not contradict the fact that every man in Paradise will have more than one wife. What is referred to by the women who will be the majority of the inhabitants of Hell is women who are descendants of Aadam: the inhabitants of Paradise will have many wives from among al-Hoor al-'Iyn.

"Women will be few among the inhabitants of Paradise because in most cases they prefer the immediate pleasures of this life, as they are less wise and unable to keep the Hereafter in mind. They are too weak to strive and prepare themselves for it, and are more inclined towards this world. In spite of all this, they are the strongest factor in this world that distracts men from the Hereafter, because men are inclined to desire them and they are not concerned with the Hereafter. They are quick to follow those who call them to deviate from Islaam, and reluctant to follow those pious people who call them to the Hereafter, and righteous deeds". (al-Qurtubee, at-Tadhkirah, 1/369)

In spite of all this, there are many righteous women among them, who stay within the limits set by Allah (swt), adhere to His laws, and obey Allah (swt) and His Messenger. Many of these women will enter Paradise, and many of them excel over men in their faith and righteous deeds.

May Rab Forgive Us All
And Bring Us On The Right Path
