34. Good deeds will be increased by ten times while Evil deeds will be given punishment equivalent to its evil

Surah No. 6, Al Anaam, Ayat No. 160

o مَن جَاء بِالْحَسَنَةِ فَلَهُ عَشْرُ أَمْثَالِهَا وَمَن جَاء بِالسَّيِّئَةِ فَلاَ يُجْزَى إِلاَّ مِثْلَهَا وَهُمْ لاَ يُظْلَمُونَ

Translation :

He, who has done good shall have ten times to his credit: he who has done evil shall only be punished equivalent to his evil. Injustice will never be done to anybody.
