As'salamu Alaikum dear brothers and sisters in Islam,
Twice
"nearest to piety"
? 

was mentioned in the Glorious Quran:
1- For forgiving others' faults and debts
??
? 

.
2- For being just and standing up for Justice

??
? 

.
See Noble Verses
2:237, 5:8.
Doing these two good deeds would bring the believing Muslim nearest to piety, insha'Allah (if Allah Almighty is Willing). Please visit:
