What did Allah's Messenger (peace be upon him) tell Ubayy b. Ka'b when He revealed to him that Allah had commanded him to recite the verse "Those who disbelieve were not..." (al-Qur'an, xcviii. 1)?
 Anas reported Allah's Messenger (may peace be upon him) as saying to Ubayy b. Ka'b:                      Aliah has commanded me to recite to you:" Those who disbelieve were not..." (al-Qur'an, xcviii. 1). He said: Did He mention me by name? He (the Holy Prophet said): Yes. Upon this he shed tears (of gratitude).
