Translation:

48. We send the Apostles only to give good news and to warn: so those who believe and mend (their lives) upon them shall be no fear nor shall they grieve.

Notes (Tafseer)

866. The Apostles are not sent to cancel man's limited free-will. They are sent to preach and teach, - to preach hope to the repentant ("good news"), and to warn the rebellious of the Wrath to come.
