Narrated Asma bint Abi Bakr: I saw Zaid bin Amr bin Nufail standing with his back against the Ka'ba and saying,   O people of Quraish! By Allah, none amongst you is on the religion of Abraham except me.   He used to preserve the lives of little girls: If somebody wanted to kill his daughter he would say to him,   Do not kill her for I will feed her on your behalf.   So he would take her, and when she grew up nicely, he would say to her father,   Now if you want her, I will give her to you, and if you wish, I will feed her on your behalf.
