The ruling on one who accuses Muslims of harshness and violence and cites the incident of Banu Nadir as an example

Question:
May Allah reward you, Your Eminence, father. The questioner asks: How do we respond to those who accuse Muslims of violence and harshness, and who cite the incident of Banu Nadir—where they were slaughtered and expelled from Madinah as a consequence of their betrayal—as an example?

Answer:
The one who says this is a disbeliever, because he has accused the Messenger (peace and blessings be upon him) of error in his actions. This makes him a disbeliever, may Allah protect us from that, because he has accused the Messenger (peace and blessings be upon him) of error in his actions. It is Allah (Exalted and Majestic is He) who commanded His Messenger to do so: So, in reality, he is denying Allah and His Messenger, and accusing the Messenger of error; therefore, he is a disbeliever without doubt. Yes.
