Abu Khaythama narrated to us, Jarir narrated to us, from Yazid ibn Abi Ziyad, from Abd al-Rahman ibn Abi Nu'm, from Abu Sa'id al-Khudri, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Al-Hasan and al-Husayn are the masters of the youth of the people of Paradise, and Fatimah is the mistress of the women of the people of Paradise, except for what was of Maryam bint 'Imran."
