وَإِذۡ قَتَلۡتُمۡ نَفۡسٗا فَٱدَّٰرَٰءۡتُمۡ فِيهَاۖ وَٱللَّهُ مُخۡرِجٞ مَّا كُنتُمۡ تَكۡتُمُونَ ٧٢
And [recall] when you slew a man and disputed1 over it, but Allāh was to bring out that which you were concealing.
Translation: Saheeh International (English)
1 i.e., exchanged accusations and denials.
Each word's meaning and sound
Allah reminds the Israelites about when they killed one of their own. They accused each other of it, each rejecting the accusation of having killed him, and accusing someone else, until they fought. But Allah revealed what they were hiding about the murder of the innocent person.
