[Fluttering black flags], is of other signs of the Last Era or the Emergence time.

It was mentioned in Shia and Sunni Narrations, [Yet, it is not from the imminent signs.]

[Those are] the flags to support and guide [people] to the path of Imam Mahdi (hgr),

which will be raised from Khorasan.

In the book “Sunan” of Ibn Mājah, [the author] wrote the Prophet (pbuh&h)’s words:

Verily my household will get into disasters, hardships and deportations after me,

Till, a group comes from the east.

They have fluttering black flags and they seek goodness…

[Finally], they entrust them [the flags] to a man of my household.

And he will fill the earth by justice…

Whoever learns [his uprising], s/ he must accompany them. Even if you move on the snow. [Even in the worst or hardest situation]”
