The Muslims from Yathrib were known from then on as Al Ansar (helpers) and those from Mecca were known as Al Muhajireen (migrants). Even the name of the city, Yathrib, was changed to Al Madinah Al Munawarah (the enlightened city).
Al Ansar were very generous to their new brothers. They shared with them everything. Including their money, farms and residence. They made them feel very happy and welcome. Rasulu Allah (saws) was very pleased with the Ansar that he once said: "Had it not been for the Hijrah, I would have been one of the Ansar".
