General Behavior (Kitab Al-Adab)

Dawud :: Book 41 : Hadith 5127

Narrated Abdullah ibn Abbas:

The Prophet (peace_be_upon_him) said: If anyone has a female child, and does not bury her alive, or slight her, or prefer his children (i.e. the male ones) to her, Allah will bring him into Paradise. Uthman did not mention "male children".
