Quran 28:84 from Surah Al-Qasas on Divine Marvels.
مَن جَآءَ بِٱلۡحَسَنَةِ فَلَهُۥ خَيۡرٞ مِّنۡهَاۖ وَمَن جَآءَ بِٱلسَّيِّئَةِ فَلَا يُجۡزَى ٱلَّذِينَ عَمِلُواْ ٱلسَّيِّـَٔاتِ إِلَّا مَا كَانُواْ يَعۡمَلُونَ
English translation: Whoever comes with a good (deed) then for him (will be) better than it and whoever comes with an evil (deed) then not will be recompensed those who do the evil (deeds) except what they used (to) do
Transliteration: man jaa bil-hasanati falahu khayrun min'ha waman jaa bil-sayi-ati fala yuj'za alladhina amilu al-sayiati illa ma kanu ya'maluna
