We were talking about Hajjat-ul-Wada`, while the Prophet (ﷺ) was amongst us. We did not know what
Hajjat-ul-Wada` signified. The Prophet (ﷺ) praised Allah and then mentioned Al-Masih Ad-Dajjal and
described him extensively, saying, "Allah did not send any prophet but that prophet warned his nation
of Al-Masih Ad-Dajjal. Noah and the prophets following him warned (their people) of him. He will
appear amongst you (O Muhammad's followers), and if it happens that some of his qualities may be
hidden from you, but your Lord's State is clear to you and not hidden from you. The Prophet (ﷺ) said it
thrice. Verily, your Lord is not blind in one eye, while he (i.e. Ad-Dajjal) is blind in the right eye
which looks like a grape bulging out (of its cluster). No doubt,! Allah has made your blood and your
properties sacred to one another like the sanctity of this day of yours, in this town of yours, in this
month of yours." The Prophet (ﷺ) added: No doubt! Haven't I conveyed Allah's Message to you? " They
replied, "Yes," The Prophet (ﷺ) said thrice, "O Allah! Be witness for it." The Prophet (ﷺ) added, "Woe to
you!" (or said), "May Allah be merciful to you! Do not become infidels after me (i.e. my death) by
cutting the necks (throats) of one another."
