Qur'an 89:22 "And your Lord has come, and the angels, rank upon rank." (Speaking about the hereafter)

Qur'anic ayat are often interpreted in many ways. Possibly, you are asking about the notion of the arrival of God, since, as a transcendent being, God does not physically arrive in a place.

Here is a narration about this verse from Imam al-Rida (A) which addresses that implicit question:

Once Imam al-Rida (A) was asked about the verse, "and your Lord has come, and the angels, rank upon rank" (89:22). He said, "Coming and going are not attributes which apply to God. Glory be to Him! He is above moving. What is meant here is that the command of your Lord comes." (Uyun Akhbar al-Rida)

That is to say, in this interpretation, "your Lord has come" is interpreted to mean "the command of your Lord has come"; it is a metaphorical use of language in the Qur'an.

Hope that helps!
