The 'inaccessible'

'And that God may help thee with inaccessible help' (48:2).
The 'inaccessible' is something desired that cannot be reached. Since the messengers are those who seek to reach him, his inaccessibility does not allow them to grasp him, because of his all-inclusive mission, God's bestowing the all-comprehensive words upon him, his lordship through the Praiseworthy Station in the next abode, and God's making his community 'the best community ever brought forth to mankind' (Qur'an 3:106) - for the community of every prophet is in the measure of the station of its prophet. So know that!
When those who maintain that prophethood can be earned sought to reach him, he was inaccessible to them. The only thing that can be earned is travelling and reaching the door. As for what lies beyond the door, those who reach the door have no knowledge of him for whom it has been opened.
