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.
