← Previous Hadith The Prophet (ﷺ) said: One night it seemed to me in a dream that we were in the house of Uqbah ibn Rafi' and were brought some of the fresh dates of Ibn tab. I interpreted it as meaning that to us is granted eminence (rif'ah) in this world, a blessed hereafter ('aqibah), and that our religion has been good (tabah).
