Translation:

7. For those who reject Allah is a terrible Penalty: but for those who believe and work righteous deeds is Forgiveness and a magnificent Reward.

Notes (Tafseer)

3879. To reject Allah is to reject all the good which He has implanted in our nature. Are we going to be false to the true Pattern according to which He created us, and suffer the consequences? Or are we going to be true to that Pattern and achieve the high and noble Destiny intended for us?
