It is narrated from Sayyidah Azzah bint Khabil (may Allah be pleased with her) that she came to the Prophet (peace and blessings be upon him) and pledged allegiance to him, and he (peace and blessings be upon him) took this pledge from her: "That you will not commit adultery, you will not steal, and you will not destroy your children, neither openly nor secretly." She said: I said: O Messenger of Allah! Destroying them openly I have understood, but destroying them secretly I have not understood, and it occurred to my mind that what is meant is ruining a child; so I never ruined any child. The narrator said: And she did not ruin any child of hers until she died. (These are the words of the narration of Ibn Abi Fudayk.)
