I asked my father, "Was the Verse:-- 'Say: (O Muhammad) Shall We tell you the greatest losers in respect of their deeds?'(18.103) revealed regarding Al-Haruriyya?" He said, "No, but regarding the Jews and the Christians, for the Jews disbelieved Muhammad and the Christians disbelieved in Paradise and say that there are neither meals nor drinks therein. Al- Hururiyya are those people who break their pledge to Allah after they have confirmed that they will fulfill it, and Sad used to call them 'Al-Fasiqin (EVILDOERS who forsake Allah's obedience).
Narrated Salim's father
That he heard Allah's Apostle, when raising his head from bowing of the first Rak'a of the morning prayer, saying, "O Allah! Curse so-and-so and so-and-so" after he had said, "Allah hears him who sendshis praises to Him. Our Lord, all the Praises are for you!" So Allah revealed:-- "Not for you (O Muhammad! )......(till the end of Verse) they are indeed wrong-DOERS." (3.128) Salim bin 'Abdullah said' "Allah's Apostle used to invoke EVIL upon Safwan bin Umaiya, Suhail bin 'Amr and Al-Harith bin Hisham. So the Verse was revealed:-- "Not for you (O Muhammad!)......(till the end of Verse) For they are indeedwrong-DOERS." (3.128)
