Sunan An-Nasa'i

It was narrated from Tariq and Muharibi that a manh said:""O Messenger of Allah, these are Banu Tha'labah who killed so and so during the Jahiliyyah: avenger us! He raised his arms until the whiteness of his armpits could be seen and said: ""No mother's sin can affect her child,"" twice. (Shaih)
