“I once asked abu Ja’far (a.s.), saying, ‘I pray to Allah to keep you well, I used to carry arms to sell to people of al-Sham. Ever since Allah has helped me to recognize the matter (Divine Authority of ‘A’immah) it bothers me, and I think I must not deliver arms to the enemies of Allah.’ He (the Imam) said, ‘You can do so because Allah repels through them our enemy and your enemy- the Romans - and sell it to them. When there is war among us, then do not carry arms to them. Those who carry arms to our enemies which help them against us, such people are like pagans.’”
