But all the Muslims agree that such verses are general in their import and that what is said therein applies to all the believers, whether they were present in the Prophet's days or not; and that this mode of address includes all the believers - in reality, not metaphorically. Reply: Yes! It is a title of honour, reserved for a selected few. But it does not mean that what is said in those verses is in any way restricted to those few.
Whatever order or prohibition is given in such verses is general and applies to all the believers. The matter of legislation - whether a given order is general or exclusive - is quite different from that of a speech - whether it is addressed to all the believers or to a few of them. Also, it makes no difference whether a verse ordaining a law is addressed to the believers ( O you who believe! )
