Quran 7:8 from Surah Al-A'raaf on Divine Marvels.
وَٱلۡوَزۡنُ يَوۡمَئِذٍ ٱلۡحَقُّۚ فَمَن ثَقُلَتۡ مَوَٰزِينُهُۥ فَأُوْلَٰٓئِكَ هُمُ ٱلۡمُفۡلِحُونَ
English translation: And the weighing that day (will be) the truth So whose (will be) heavy his scales then those [they] (will be) the successful ones
Transliteration: wal-waznu yawma-idhin al-haqu faman thaqulat mawazinuhu fa-ulaika humu al-muf'lihuna
