Ikrimah (may Allah have mercy on him) said: Sayyiduna Ibn Abbas (may Allah be pleased with them both) was asked: Do the non-Arabs have the right to erect a building or a church in the cities of the Muslims? He said: As for the cities which the Arabs founded, the non-Arabs have no right to put up a building in that city, or he said: to build a church in them. Nor may they strike the clapper (naqus) in it, nor may they drink wine in it, nor may they keep swine in it, or he said: nor may they bring swine into it. And as for the city which the non-Arabs founded, then Allah gave the Arabs dominance over it and they surrendered to the ruling of the Arabs, the non-Arabs have the right to act according to the covenant made with them. And the non-Arabs have the right over the Arabs that they fulfil their covenants with them. And they must not burden them beyond their capacity.
