Hazrat Abu Hanzala bin Naeem (may Allah have mercy on him) narrates that Hazrat Saad (may Allah have mercy on him) wrote a letter to Hazrat Umar (may Allah be pleased with him) saying that we have taken control of a region without fighting. What should we do now? Hazrat Umar (may Allah be pleased with him) replied to them in a letter: If you wish to divide this region among yourselves, then divide it, and if you wish, leave this region so that its inhabitants themselves will settle it. And if someone joins you in this region after you have received your share, then I fear that you will compete with each other in this matter and in the distribution of water, and then some of you will kill others. Hazrat Saad (may Allah have mercy on him) wrote a letter to him (may Allah be pleased with him) and said: Indeed, all the Muslims have agreed that their opinion is subject to your (may Allah be pleased with him) opinion.

Hazrat Ikrimah (may Allah have mercy on him) narrates that he asked Hazrat Ibn Abbas (may Allah be pleased with them both): Do non-Arabs have the right to build any building or church for Muslims in the cities? He (may Allah be pleased with him) replied: As for those cities which the Arabs have settled, non-Arabs do not have the right to build any building in those cities, or he said: to build churches in them. Nor can they ring bells in them. Nor can they drink wine in them, nor can they keep pigs in them, or he said: nor can they bring pigs into them. And as for those cities which the non-Arabs have settled, then Allah gave the Arabs dominance over them and they settled in those cities, then the non-Arabs will have the right to do according to the agreement made with them. And the non-Arabs have a right over the Arabs that they fulfill their promises to them. And do not burden them with more than they can bear.
