Surah 27. An-Naml, Ayah 38

I.e., evidently in response to his message (Razi, Ibn Kathir).

Lit., "before they come unto me as people who surrender themselves (muslimin)" i.e. to God (see verse {31} above). The term "throne" ('arsh) is used here and in the sequence - as well as at the end of verse {23} - in its metonymic sense of "dominion" or "regal power" (Raghib). It appears that Solomon intends to confront his guest with an image of her worldly power, and thus to convince her that her "throne" is as nothing when compared with the awesome almightiness of God.

 To explain why Prophet Solomon brought the Queen’s magnificent throne and built the marvellous palace, many traditional commentators cite some folkloric or legendary stories. However, none of these stories is supported by reliable Islamic sources.

The throne is symbolical of power and dignity. So far her throne was based on material wealth: Solomon is going to alter it to a basis of Faith and the Religion of Unity.
