Dawud :: Book 18 : Hadith 2900
Narrated Wathilah ibn al-Asqa':
The Prophet (peace_be_upon_him) said: A woman gets inheritance from the three following: one she has set free, a foundling, and her child about whom she has invoked a curse on herself if she was untrue in declaring he was not born out of wedlock.
