Musnad Ahmad 1156:143

Narrated to us by Abd al-Rahman, from Sufyan, from Habib, from Sa'id ibn Jubayr, from Ibn Abbas, who said: The Messenger of Allah (ﷺ) said: "I was shown the Fire, and I have never seen a more terrifying sight than it. And I saw that the majority of its inhabitants were women." They said: "Why, O Messenger of Allah?" He said: "Because of their ingratitude (kufr)." It was said: "Do they disbelieve in Allah?" He said: "They are ungrateful to their companions, and they are ungrateful for kindness. If you were to treat one of them kindly for an entire lifetime, then she saw something in you [that she disliked], she would say: 'I have never seen any good from you.'"
