Surah 85. Al-Buruj, Ayah 20

Lit., "from behind them", an idiomatic phrase denoting a happening imperceptible to those whom it closely concerns.

Allah encompasses every thing. But the wicked will find themselves defeated not only in conditions that they foresee, but from all sorts of unexpected directions, perhaps from behind them, i.e., from the very people or circumstances which in their blindness they despised or thought of as helping them.
