Narated By AbuHurayrah : The Apostle of Allah (pbuh) said: When one of you recites "By the fig and the olive" (Surah 95) and comes to its end "Is not Allah the best judge?" (verse 8), he should say: "Certainly, and I am one of those who testify to that." When one recites "I swear by the Day of Resurrection" (Surah 75) and comes to "Is not that one able to raise the dead to life? (verse 40), he should say: "Certainly." And when one recites "By those that are sent" (Surah 77), and comes to "Then in what message after that will they believe?" (Surah 50), he should say: "We believe in Allah."
The narrator Isma'il (ibn Umayyah) said: I beg to repeat (this tradition) before the Bedouin (who reported this tradition) so that I might see whether he (was mistaken).
He said: My nephew, do you think that I did not remember it? I performed sixty hajj (pilgrimages); there is no hajj but I recognize the came on which I performed it.
