Al-Baqarah - 2:72

وَإِذْ قَتَلْتُمْ نَفْساً فَادَّارَأْتُمْ فِيهَا وَاللّهُ مُخْرِجٌ مَّا كُنتُمْ تَكْتُمُونَ
[2:72]
And when you killed a man, then you disagreed with respect to that, and Allah was to bring forth that which you were going to hide.
Remember ye slew a man and fell into a dispute among yourselves as to the crime: But Allah was to bring forth what ye did hide.
And (remember) when ye slew a man and disagreed concerning it and Allah brought forth that which ye were hiding.
