Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said:
"Whoever reviles my Companions, upon him will be the curse of Allah Almighty, the angels and all mankind."
Al-Tabarani recorded it; its chain contains a narrator, Abdullah bin Khirash, who is da'if (weak).
(Allamah al-Haythami says:) I say: Some hadith of this kind have already passed earlier, in the chapter on the virtue of the Companions.
