Musnad Ahmad 28:231

Rawh narrated to us, Ibn Jurayj narrated to us, from ‘Amr ibn Shu‘ayb, from his father, from his grandfather ‘Abdullah ibn ‘Amr: That a woman came to the Prophet, may Allah bless him and grant him peace, and said: "O Messenger of Allah, this son of mine—my womb was a vessel for him, my lap was a shelter for him, and my breast was a waterskin for him. Yet his father claims that he will take him away from me." He said: "You have more right to him, as long as you do not remarry."
