Imam Ahmad recorded from Anas bin Malik that the Messenger of Allah said to Ubayy bin Ka`b,
(Verily, Allah has commanded me to recite to you (Those who disbelieve from among the People of the Scripture.)) Ubayy said, "He (Allah) mentioned me by name to you'' The Prophet replied,
(Yes.) So he (Ubayy) cried. Al-Bukhari, Muslim, At-Tirmidhi and An-Nasa'i all recorded this Hadith from Shu`bah.
In the Name of Allah, the Most Gracious, the Most Merciful.
