[16].Surah An-Nahl [The Bees] : Ayat 95-96

Ayat 95. And purchase not a small gain at the cost of Allah's Covenant. Verily! What is with Allah is better for you if you did but know.

Ayat 96. Whatever is with you, will be exhausted, and whatever with Allah (of good deeds) will remain. And those who are patient, We will certainly pay them a reward in proportion to the best of what they used to do .

Hazrat Abu Dharr and Mu`adh bin Jabal (May Allah be pleased with them) reported that: Messenger of Allah [SAWW](PBUH) said, "Fear Allah wherever you are, do good deeds after doing bad ones, the former will wipe out the latter, and behave decently towards people" [At-Tirmidhi Hadith # 1987]. 

Lesson : as mentioned above in Surah An-Nahl Ayat 95.Verily! What is with Allah is better for you if you did but know. Virtue obliterates vice means that virtue becomes an atonement for sin. But this applies to minor sins only because major ones will not be forgiven without sincere repentance. Similar is the case of encroachment on public rights which will not be forgiven without their compensation.
