Quran 2:72 from Surah Al-Baqara on Divine Marvels.
وَإِذۡ قَتَلۡتُمۡ نَفۡسٗا فَٱدَّٰرَٰٔتُمۡ فِيهَاۖ وَٱللَّهُ مُخۡرِجٞ مَّا كُنتُمۡ تَكۡتُمُونَ
English translation: And when you killed a man then you disputed concerning it but Allah (is) the One Who brought forth what you were concealing
Transliteration: wa-idh qataltum nafsan fa-iddaratum fiha wal-lahu mukh'rijun ma kuntum taktumuna
