The Duty of a Host When the Food of Their Guest Is Najis
Issue No.157- If a host comes to know, while having a meal, that the food is najis, he must inform the guests about it, as an obligatory precaution. If, however, one of the guests becomes aware of this fact, he must refrain from eating but it is not necessary to inform the rest about it. However, if his interaction with the other guests is such that he himself may become najis, he can inform them about the najāsah of the food when the meal is over so that they rinse their hands and mouths.
