Abu Dawud Book 6, Hadith Number 2269.

Narated By Abdullah ibn Amr ibn al-‘As : A woman said: Apostle of Allah, my womb is a vessel to this son of mine, my breasts, a water-skin for him, and my lap a guard for him, yet his father has divorced me, and wants to take him away from me. The Apostle of Allah (PBUH) said: You have more right to him as long as you do not marry.
