Can I eat with someone who does not offer his prayer? I have heard from someone that you cannot eat with such a person, i.e. one who does not perform Namaz.
It is permissible to eat with someone who does not offer Namaz. However, if one refrains from eating with such a person to reprimand him from this sinful act, then there is no problem in adopting this course of action.
And Allah knows best.
