The Messenger of Allah ﷺ once sat in a gathering and spoke to them about the one-eyed Dajjal. Among what he mentioned was, "Whoever is present at my gathering and hears my words, let those of you who are present convey this to those who are absent. Know that Allah is sound and is not one-eyed, but the Dajjal is one-eyed, with his eye effaced. Between his eyes is written 'disbeliever,' which every believer will read, whether literate or illiterate."
أن رسول الله ﷺ جلس مجلسا مرة يحدثهم عن أعور الدجال فمما ذكر فيه: فمن حضر مجلسي، وسمع قولي فليبلغ الشاهد منكم الغائب، واعلموا أن الله عز وجل صحيح ليس بأعور، وأن الدجال أعور ممسوح العين، بين عينيه مكتوب كافر يقرؤه كل مؤمن كاتب وغير كاتب.
Imam Ahmad narrated it (27585), and Tabarani in Al-Kabir (24/177), and Harith in his Musnad - its supplementary reports (783) - all of them through routes going back to Abdul-Hameed bin Bahram, who said, Shahr bin Hawshab narrated to us, saying, Asma bint Yazid narrated to me, and he mentioned it.Shahr bin Hawshab is present in it, and there is disagreement about him, with the majority inclined toward weakening him, because he was accused of making mistakes. So when sahih corroborating narrations are found for something of his, that means he did not err in that particular instance, and this is one of those cases.
