Sayyiduna Abu Hurairah (may Allah be pleased with him) says: I went towards the mountain and met Ka'b al-Ahbar. I sat with him; he narrated to me things from the Torah and I narrated to him the hadiths of the Messenger of Allah (peace and blessings be upon him). I also told him that the Messenger of Allah (peace and blessings be upon him) said: The best day on which the sun rises is Friday. On this day Adam (peace be upon him) was created, on this day he was sent down (to earth), on this day his repentance was accepted, on this day he passed away, and on this day the Resurrection will be established. On this day, from morning until sunrise, every creature listens attentively out of fear of the Resurrection, except jinn and mankind. On this day there is an hour in which, whatever Muslim prays to Allah Almighty, He grants it to him. Ka'b said: This hour occurs once in a year. I said: Rather, it occurs every Friday. Then Ka'b read the Torah and said: The Messenger of Allah (peace and blessings be upon him) has spoken the truth (it really does occur every Friday). Sayyiduna Abu Hurairah (may Allah be pleased with him) says: Then I met Sayyiduna Abdullah bin Salam (may Allah be pleased with him). I told him about my gathering with Ka'b and the discussion about Friday that took place in it, and said that Ka'b said this hour occurs once in a year. Upon hearing this, Sayyiduna Abdullah bin Salam said that Ka'b was mistaken. I said: Yes, then he read the Torah and said that indeed it occurs every Friday. Upon hearing this, he said: Ka'b has spoken the truth.
