What is the ruling on a Muslim hosting People of the Book and disbelievers in his home, and is it obligatory to honor the disbeliever for three days, then encourage him to embrace Islam for ten days, and what should the Muslim do with them after that?

Scholars have differed regarding the ruling on hospitality. The majority are of the opinion that it is recommended (mustahabb), while the Hanbalis are of the view that it is obligatory (wajib (definition)) with regards to a Muslim, but not a non-Muslim. And in one narration, it is obligatory with regards to both the Muslim and the non-Muslim. This obligation is restricted to villages, while in cities (amsar), hospitality is not obligatory according to the correct view. The obligatory amount is for one day and night, and it is recommended for three days, and anything beyond that is charity (sadaqah (definition)). So, it is recommended to honor the guest and treat him well for a period of three days, and whatever exceeds that is charity. What should be done towards the non-Muslim is to invite him to Islam with wisdom and good exhortation, and to treat them in the best manner. It is not permissible to initiate the greeting of peace (salam) to them, and if they greet you, then say "wa 'alaykum" (and upon you). It is permissible to visit them when they are sick and offer them Islam, and to congratulate them on a spouse, or a child, or the arrival of someone who was absent, or safety from harm, while being cautious of words that indicate approval of their religion. Congratulating them on rituals of disbelief (kufr) is unanimously prohibited. One should have the intention of inviting them to Islam present in one's mind.
