“I once said to abu ‘Abd Allah (a.s.), that we often meet a people from the mountains, the distance between us is quite far to the mountains by many Farsakh (a certain unit of measurement for distance). We buy one, two or three flocks and every flock numbers one thousand five hundred, one thousand six hundred or one thousand seven hundred sheep. Then two or three sheep are cut (killed) and we ask the shepherd about their religion. They say that they are Christians. What do you say about the slaughtering by Jews and Christians? He (the Imam) said, ‘O al-Husayn, ‘Slaughtering is by name and no one can be trusted in this matter except people who believe in the Oneness of Allah.’”
