Musnad Ahmad 1119:22

'Ali ibn 'Asim narrated to us, he said: An-Nahhas ibn Qahm informed me, from Abu 'Ammar Shaddad, from 'Awf ibn Malik, he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever has three daughters or three sisters, or two daughters or two sisters, and he fears Allah regarding them and treats them well until they depart or die, they will be a shield for him from the Fire."
