Hadith 1819

'Abdullah bin 'Umar (May Allah be pleased with them) said: One day the Messenger of Allah (PBUH) 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."
