On page 17 of the Qur'an, Allah reminds us that whenever a verse is abrogated or forgotten, He replaces it with a better or similar one. This emphasises Allah's limitless authority. The verses also assert that Allah alone holds dominion over the heavens and the earth, and there is no protector or helper besides Him.
The verse challenges those who wish to question the Messenger, comparing it to the query posed to Musa. Changing faith for disbelief leads one astray. Some of the people of the Scripture may envy and attempt to turn believers away, but forgiveness is advised until Allah's command prevails.
Further, performing prayers, giving Zakat, and sending forth good deeds are highlighted as actions rewarded by Allah. The notion that only Jews or Christians will enter Paradise is refuted; submission to Allah and virtuous conduct lead to reward without fear or grief.
