«لا ترجعوا بعدي كفارا يضرب بعضكم رقاب بعض ولا يؤخذ الرجل بجريرة أبيه ولا بجريرة أخيه»
The Prophet (peace and blessings be upon him) said:
"Do not become disbelievers after me, striking the necks of one another. And a man is not to be held accountable for the crime of his father, nor for the crime of his brother."
