Well, as you well know, ''alameen' is the plural of ''alam,' and each 'alam' is a 'realm' or 'world' of existence: the 'world' of men and the 'world' of jinn. Seems to me that the verse means that Muhammad is not just a warner to the world of men alone, but to jinn also; a warner to all worlds, just as Allah is the 'Rabb' of all worlds. As for the angels, it goes without saying that they don't have warners, as they have no need, but the Qur'an makes it clear that both men and jinn are sent messengers:
True it is in a plural form, and realm (of men) is not all men. Only *all the realms* (of men) includes all men. It’s like saying he was sent to *the entire world*. See for example 3:20; 7:80. In fact, it can even simply mean *people*. See for example: Prophets:71; Poets:165; Hijr:70.
[6:130]
’Company of jinn and mankind, did not Messengers come to you from among you, relating to you My signs and warning you of the encounter of this your day?’ They shall say, ’We bear witness against ourselves.’ They were deluded by the present life, and they bear witness against themselves that they were unbelievers.
thanks for the verse!
