(Killing the Forced into War is not of Islam)
The Prophet advised his companions in the battle of Badr saying, "I have come to know that some people from Banu Hashim and others were forced to accompany the pagans, although they had no desire to fight against us. Therefore, whoever meets any of them (Banu Hashim), do not kill him. Whoever meets Abu Al-Bukhtari ibn Hisham, he should not kill him. Whoever meets Al-Abbas ibn Abdul-Muttalib, the Prophet's uncle, let him not kill him, for he was forced to come (with the pagan army) ."
