As a necessary corollary to the recognition of universal brotherhood of the human race under the common Laws of Almighty Allah , Islam throws open its dining mat to all irrespective of caste, creed, colour and social position. Every member of the Islamic Commonwealth is equally entitled to partake of his food in the same dining mat.
The Apostle of Allah (sallal laahu alaihi wasallam) had a big tray, which could be carried by four men. All the Muslims present used to partake of food in that tray, each man eating from its side. So far as the dining table of the followers of other religions is concerned, the Muslims are allowed to partake of their food except what has been made unlawful to be placed in the dining mat of the Muslims themselves.
The Holy Quraan has not at all prohibited this inter-dining, nor has the Hadith. On the contrary, the Holy Quraan declares: “This day all the good things are allowed to you, and the food of those who have been given the Book is lawful for you, and your food is lawful for them.” (5:5)
Sayyiduna Abu Th’alabah (radi Allahu anhu) reported: I asked: O Messenger of Allah (sallal laahu alaihi wasallam)! We are certainly travellers and pass by the Jews, Christians and the Magians. So we don’t find but their utensils. He replied: If you don’t find other than those things, wash them with water and eat and drink in them. (Tirmidi)
