Musnad Abu Ya'la al-Mawsili 117:174

Shayban narrated to us, Muhammad ibn Ziyad al-Burjami narrated to us, Thabit narrated to us, from Anas, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Whoever has three daughters or three sisters, and he fears Allah regarding them and upholds [his duties] toward them, he will be with me in Paradise like this." And he gestured with his index and middle fingers.
