آداب الزيارة والاستئذان
Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) said: "Take no companion except a believer and let no one eat your food except an Allah-fearing person.’"  
عن أبي سعيد الخدري -رضي الله عنه- عن النبي -صلى الله عليه وسلم- قال: «لاَ تُصَاحِب إِلاَّ مُؤْمِنًا، وَلاَ يَأْكُل طَعَامَكَ إِلاَّ تَقِي».

شرح الحديث :


This Hadīth urges Muslims to associate with good people. This requires refraining from accompanying the disbelievers and the hypocrites, because their companionship affects one's religiousness. The 'believer' in this Hadīth refers to any number of believers. The necessity of seeking the company of the righteous was confirmed even more by “and let no one eat your food except an Allah-fearing person,” meaning: a pious person who puts his energy in worshiping Allah. Therefore only faithful and righteous people should be invited to eat.
