Concise Quran Commentary
Whoever brings a good deed on the Day of Judgment, such as prayer, Zakat, fasting and so forth, for him is a good reward for that good deed, where the good deed will be multiplied to ten the like thereof. And whoever brings a bad deed on the Day of Judgment, such as disbelief, consuming interest, adultery and so forth, then those who did bad deeds will not be rewarded except as much as they did, without any increase.
