If you are certain that the income of the invitee is doubtful then in such case there is no harm in skipping his invitation. It is not good to doubt unnecessarily about the income of a Muslim and avoid his invitation without any reason specially when the other member of jamat are accepting his invitation. Sometimes such type of precaution hurts the invitee or the other friends dislike it.
