Abu Ayyub al-Ansari (RA) reported Allah's Messenger (ﷺ) as saying: He who observed the fast of Ramadan and then followed it with six (fasts) of Shawwal it would be as if he fasted perpetually.
Abdullah b. Umar told that Allah's Messenger (ﷺ) stood up amongst the people and lauded Allah as He deserved, then he made a mention of the Dajjal and said: I warn you of him and there is no Prophet who has not warned his people against the Dajjal. Even Noah warned (against him) but I am going to tell you a thing which no Prophet told his people. You must know that he (the Dajjal) is one-eyed and Allah, the Exalted and Glorious, is not one-eyed.
