If they touched the food, then it is not permissible to consume it nor is it permissible to consume meat presented by them, unless it was slaughtered according to the Islamic laws, which can be known if the meat is purchased from a Muslim market.
Narrations differ in the matter of Mukhtar. Some narrations praise him and others do not. In one narration, his son asked Imam Jaffer Al-Sadiq (peace be upon him) about his father. Imam replied by praising him. It appears from this that he is considered as a believer and a follower of the path of the Ahlulbait (peace be upon them).
The Sunnis are not the enemies of the Ahlulbait (peace be upon them) even if they did not follow them or believe in their Imamate. They â€“ in general â€“ love the Ahlulbait. Our Imams (peace be upon them) ordered us to associate with them in kindness and to communicate with them regularly. It was reported in an authentic narration that one of the companions asked Imam Al-Sadiq (peace be upon him):
How should we fare with each other, with our own people and with people who do not espouse our beliefs?â€ The Imam (peace be upon him) said, "You should look up to your Imams whom you follow and do as they do. By Allah, they visit their [non-followers] sick, attend their funerals, testify for or against them and return the trust to them".
The enemies of the Ahlulbait are those who hate them and bear animosity with them. They are known by their names and personalities in the books of history and biographies. There were many rulers who acted with hostility against the Imams (peace be upon them) that lead to the Imams being killed, expelled and imprisoned. This can be found by referring to history books.
