When Prophet Moosa (AS) was born, his mother put him in a water proof box and placed the box on the river Nile . She then sent her daughter to follow the little "boat" and see where it went.
The box floated towards the palace of Fir'aun , where his men fished it out and brought the baby to him. He wanted to kill it immediately, suspecting that it might be a child of the Bani Israa'eel, but his wife Aasiya, who was a pious woman, stopped him. They did not have children of their own, so she asked him to adopt the child.
Fir'aun agreed to his wife's request and then called some women to breast feed the crying child. However, the baby refused milk from all the women who came to feed him, except his mother. So Allah reunited mother and child in the very palace of Fir'aun.
