When they went in unto him and said, "Peace!" he replied, "Peace:-they are strangers."

According to the Quran, when unknown guests — angels bearing good news — come to Abraham’s house, the first word exchanged is “Peace!” (Salam), and Abraham, without knowing them, at once serves them the best he has. Today, welcome someone, even a stranger, with a word of peace and a concrete gesture of hospitality: a smile, a glass of water, a place at your table.
