Musnad Abu Ya'la al-Mawsili 161:3

Sulayman ibn Abd al-Jabbar Abu Ayyub narrated to us, Ya'qub ibn Ishaq al-Hadrami narrated to us, from Abd al-Salam ibn 'Ajlan al-Hujaymi, Abu 'Uthman al-Nahdi narrated to us, from Abu Hurayrah, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "I am the first person for whom the gate of Paradise will be opened, except that a woman will come and hasten before me. So I will say to her: 'What is the matter with you? Who are you?' She will say: 'I am a woman who sat [in patience] over orphans of mine.'"
