Al-Tufayl reported: I would come with Abdullah ibn Umar, may Allah be pleased with him, to the market and when we did so, Ibn Umar would not pass anyone but that he would greet them with peace, whether they were selling merchandise or were poor. I came to Ibn Umar one day and asked him to follow me to the market. I said, “What will you do in the market, if you will not sell or buy or barter or sit in the gatherings?” Ibn Umar said, “O you with a big belly, we only go out in the morning to greet them with peace. We greet with peace whomever we meet.”

Ibn Abdul Barr said, “It is narrated from Ibn Mas’ud, Abu Darda, and Fadalah ibn ‘Ubayd that they would initiate the greeting of peace with non-Muslim citizens. Ibn Mas’ud once wrote to a man among the people of the Book and he said: Peace be upon you.”
