Al-Sharwgy 313 (Asaib Ahl al-Haq — unofficial leadership signal channel) posted this afternoon that in the battle of Siffin, when Ammar ibn Yasir was killed, Mu'awiya said it was Ali and his companions who killed him by bringing him to the battlefield, and that today "some repeat, most regrettably, the saying of Mu'awiya — may God's curse be upon him — and accuse 'the insolent militias'" while themselves being counted among Ali's camp. The post says the sacrifices of "the front of right" should not produce a feeling of weakness and fracture but more steadfastness and serious work to overcome failures and weak points "by realistic methods far from illusions, as the religious authority expressed it." No individual, faction or institution is named.
The channel's own words place a live argument over responsibility for setbacks inside the Shia camp rather than between the factions and their declared enemies.
