The Messenger of Allah (ﷺ) said: "Indeed the one who betrays will have a banner erected for him on the Day of Judgement."

[He said:] There are narrations on this topic from 'Ali, 'Abdullah bin Mas'ud, Abu Sa'eed Al-Khudri, and Anas.

[Abu 'Eisa said:] This Hadith is Hasan Sahih. I asked Muhammad about the Hadith of Suwaid, from Abu Ishaq, from 'Umarah bin 'Umair, from 'Ali, from the Prophet (ﷺ) who said: "For every person who betrays there will be banner." He said: "I do not know of this Hadith being Marfu'"
