Musnad Abu Ya'la al-Mawsili 110:245

Zuhayr narrated to us, Jarir ibn Abd al-Hamid narrated to us, from Fitr, from Shurahbil ibn Sa'd, from Ibn Abbas, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "There is no Muslim who has two daughters and treats them well as long as they accompany him or he accompanies them, except that they will cause him to enter Paradise."
