Umar ibn Al-Khattab said: Captives were brought to the Prophet صلى الله عليه وسلم after a battle. Among them was a woman desperately searching for something. When she laid her eyes on a baby she immediately picked it up, clutched it to her breast and started feeding it. Thereupon, the Prophet صلى الله عليه وسلم asked, “Do you think this woman would throw her child into a fire?” We said, “Never! By Allah!” The Prophet صلى الله عليه وسلم then said, “Allah is more merciful to His slaves than this woman is to her child.”
