When you ran off precipitately and did not wait for any one, and the Messenger was calling you from your rear, so He gave you another sorrow instead of (your) sorrow, so that you might not grieve at what had escaped you, nor (at) what befell you; and Allah is aware of what you do.

If you call on them they shall not hear your call, and even if they could hear they shall not answer you; and on the resurrection day they will deny your associating them (with Allah); and none can inform you like the One Who is Aware.
