2-Surah Al-Baqarah ( The Cow ) 73
So, We said, ‘ Strike the slain man with part of it.’ Thus does Allah bring the dead to life, and He shows you His signs that you might reason.
فَقُلْنَا اضْرِبُوهُ بِبَعْضِهَا ۚ كَذَٰلِكَ يُحْيِي اللَّهُ الْمَوْتَىٰ وَيُرِيكُمْ آيَاتِهِ لَعَلَّكُمْ تَعْقِلُونَ
Quran's Tafhim ( explanation)
*85). At least one thing becomes clear from this statement: that the slain person was restored to life at least long enough to indicate his assassins. But the actual words in which the order 'smite the corpse with a part of it' is couche tend to create a measure of ambiguity. Nevertheless, the meaning inferred by the early Qur'anic commentators - that the order was to smite the slain man's body with some part of the slaughtered cow - seems to me plausible. Two birds were thus killed with one stone: first, they were made to behold a sign of God's power; and second, the notion that the cow possessed any holiness or sanctity was shattered. For if the of the object of their worship - the cow - had any supernatural power, some calamity should have visited them as a consequenceof slaughtering it. But no calamity took place. On the contrary, killing the cow seemed to be beneficial insofar as striking a dead man with a part of it brought him back to life.
