Riyad as-Salihin 18:12

'Abdullah bin 'Umar (May Allah be pleased with them) said:

One day the Messenger of Allah (ﷺ) mentioned Al-Masih Dajjal (the Antichrist) in the presence of the people and said, "Verily, Allah is not one-eyed but Al-Masih Ad-Dajjal is blind in the right eye which looks like a swollen grape." [Al-Bukhari and Muslim]
